Solutions, Dilutions and molarity calculations

Why is a conical flask, rather than a beaker, used in the experiment? – To allow easy mixing of solutions by swirling. 2. Why is the funnel removed from the burette after adding the acid solution? – so that the drops from the funnel will not fall into the burette. 3. In using a burette, why is it important to (a) rinse it with a little of the solution it is going to contain? – to remove any residual water and so avoid dilution of the acid solution when it is poured into the burette. (b) to clamp it vertically? – to enable the liquid level to be read correctly. ) to have the part below the tap full? – to ensure that the actual volume of liquid delivered into the flask is read correctly. 4. Give one reason for carrying out the following procedures during the titration. (i) The sides of the conical flask were washed down with deionised water? – To ensure that all of the acid added from the burette can react with the base. (ii) The conical flask was frequently swirled or shaken? – To ensure complete mixing of the reactants. 5. Why is a rough titration carried out? – To find the approximate end point.This nformation enables the subsequent titrations to be carried out more quickly. 6. Why is more than one accurate titration carried out? – To minimise error by getting accurate readings within 0. 1-3 cm of each other. 7. Explain why hydrochloric acid is not used as a primary standard? – The exact concentration of any hydrochloric acid solution is not known, unless it is prepared from standard ampoules. Laboratory grade hydrochloric acid is not sufficiently pure. 8. Can any of the following be used as primary standards: NaOH, H2S04, HN03? Explain your answer.A primary standard should be available in a highly pure state and stable. None of these substances are available pure because: (a) NaOH readily absorbs water and carbon dioxide from the air. (b) Concentrated H2S04 readily absorbs water from the ai r. (c)HN03 breaks down releasing N02 gas. 9. If you used only 10cm3 of sodium carbonate solution in the conical flask, calculate how much acid would be required to neutralise it. x 10-3 moles Na2C03 10cm3 Na 2CO 3 solution used at concentration of 0. 1 M 1 2 x 10-3 moles HCL required Concentration of HCL is 0. M 1000 x 2 x 10-3 / 0. 23crn3 required = 10. 5crn fi13. 10. Describe briefly how a pure dry sample of sodium chloride could be obtained having carried out the titration? – Using the information provided by the titration results, add Just enough hydrochloric acid to exactly neutralise 25cm 3 of sodium carbonate. The indicator should not be added. Gently heat the solution until all the water has evaporated to dryness. A sample of sodium chloride will remain in the beaker.

Allegory or Reflective Metamorphic Essay on What Ways I am a Prisoner

Waking up in the morning is may be the easiest part of my day. Going through the whole day, every day of my life is the hardest. This is the life of a prisoner, but I am not the typical behind-the-bars crook; I am a prisoner of my own life, with just a peephole as my only chance of escape. It’s not that I hate my life or people around me, it’s just that, I think I could be more than what I am today, that continuing this kid of life that I have is like wasting precious sands of the hour glass.This is not some wild imagination, not just some long shot hope, for I am now creating away out of this prison, making the peephole wider, so that my body could go through. I am currently employed full time, living a life with my family of three kids, one is 8 years old, another 2 years old, and the youngest is just 10 months old. I can say that I can go by everyday with what I do for a living, but still, there are some things missing in my life. I can feel it – even though I can’t see it, I know that it does exist.That’s the point where I realized that I am living my life in prison. Something is hindering me from freedom, from fully discovering myself and my potentials. Even though I have a happy family, it is like its being overshadowed by that desire to break free from prison. A life in prison for me is a typical day doing the same things over and over again. I wake up; spend a little time with my beloved family, and eventually spending the biggest chunk of my day at the work place. Sometimes, I ask myself, does everyone feel like this.Am I supposed to be doing the same things over and over again, spending my time alone, away from my family in order to make some money? I kept asking this question for so many times, but still, the answer just won’t pop in my head. What do I need to do? I feel like I am behind the cold steel bars, locked up away from the real world, forced to live a life under a routine, doing the same things over and over again for so many days. Not a day was different, with no means of escape, no way to fight for my way out.I was living a life of a free man struggling to be freed from an unknown prison which only he knows about it. By the end of the day, I am exhausted, drained to the bones. I can’t spend more time with my family because I have to sleep in order to wake up early for tomorrow’s work. I wanted to spend more time with them, but I can’t; I think this is a consequence of being a prisoner (Anonymous). You can’t decide on the things you really want to do. You have to go by the routine, or else you’ll suffer. For me, suffering is hard because it will not be felt by me alone.It will also affect my family, my loved ones, because they depend on me for sustenance so that they could grow into healthy, normal, free people. I think about them so much, and then I realize that I can’t stop now. I shouldn’t be selfish; if I only think about my self, then my family will suffer. I think a lot, maybe this is what prisoners do with their spare time. Unfortunately, thinking a lot also has its consequences. It keeps me from falling asleep, which is very bad in my case. You see, sleeping has been the only luxury that a prisoner can enjoy.He can be at peace with himself and with his surroundings. He is at ease, blissfully resting the night through, wishing that it would be longer so that his tired body will regain its energy to the fullest. It also gives the prisoner something that he could hold on to for a while, something that he could really treasure. Being in prison you learn to value sleeping because it is where his dreams are made. Dreams for me come in different forms. It could be about the things that make me happy, or be about my family’s happy moments.Sometimes, it could bring about nightmares, but I’ve learned that if you live a life of a prisoner, you learn not to fear these nightmares. Sleeping is only about dreams, and these dreams not only bring about happiness, it can also give you a little bit of hope, and maybe a glimpse of what lies ahead in the future. There was one time when I dreamt about my life, about being a prisoner (Brians). It gave me a clear view of what my real problem was, the reason I became a prisoner in my own life. It was because of my lack of education which has brought me behind bars.It gave me a clear mental picture of what it’s like if had finished schooling. I could be someone else, be someone better. I could have a chance in landing a better job, and possibly a better life. I can make the most of what I do, and I can make my family happier. It wasn’t just a dream because it showed me the way. It is reality – I can make everything real. Everything is possible, as long as I believe that I can. Armed with the dream of finishing school, I packed up everything I need. It would require all of my wits, my confidence and my willingness to p ursue this dream. Luckily, I have everything I need with me.That’s why I took the step which I know would take me out of this prison. Through the small peephole of my dream, I will make a larger hole, in which I can pass through and be free from this prison. It was the lack of education that has kept me well behind bars. It’s now my time to escape. Works Cited: Anonymous. â€Å"Prison Vs. Work†. 2007. September 15 2007. . Brians, Paul. â€Å"Plato: The Allegory of the Cave, from the Republic†. 1998.

The Realtionship of a Father and Son in Homer’s Odyssey Essay

With time come change, change in the human experience. That fact applies no differently to literature, specifically reflected through reading ancient prose with a modern lens. A relevant example is the relationship of a father and son in Homer’s Odyssey. Through characterization on the surface, this significant relationship appears quite distinct in contrast to such relationships today. However, these quite humane and sentimental relationships are no different than those experienced today—those of a father and son. Quite frankly, what is true of humans in the ancient world is true to humans today, ability to feel such potent emotion, to experience such a significant relationship yields the human need of affection and connection, as†¦show more content†¦It is a substance filled human relationship which involved much, almost as the modern day phrase â€Å"keep it real† suggests, the true emotion, a sense of sanctuary, protection and understanding between t he two, almost a notion of equality, recognizing each for his talents, finding respectability thereof. During this bond, Telemachus fills a gap that had lingered in his identity, especially through the foundation of his life, the bleeding gap of not having a father present, to fill that gap, that gap of understanding and companionship. A germane example would be that moment in today’s world that a parentless child, being instilled from place to place, is finally able to call a family his home. It is comparable to that emotional bonding time of that child, who has just been gifted with the ability to make that connection. It is that time of true human emotion that fills not only the moment, but the void, just as experienced by Odysseus and Telemachus. This special bond is so significant, the void thereof can be deemed impossible to fill. The emotion portrayed through this affectionate relationship is no different than that experienced by humans in ancient times. However, the patriarchal climate of Ancient Greece makes room for discrepancy in the emphasis of such relationships, in the difference of values and beliefs. In Ancient Greece, the son was a prized possession, almost a material of the father, expected to

The parents may feel stress as there could be only one income coming in instead of two as the baby feels what the parents , especially the mother feels, the baby will become stressed too and may not feel safe and secure in it’s environment causing the baby to feel unsettled. A mother having to go to work to keep up with the economic pressures of owning material things such as a house and car, when the baby is only a few months old could cause the mother and baby to become less attached, once again leaving the baby to feel insecure and unsettled.

What is Strategy by Michael Porter

Michael porter has outlined strategy in a broad way. His work is based on research into various companies and industries. In his discussion, he has managed to put together a variety of ideas that have helped him come up with tangible definitions of strategy and management issues. This essay defines strategy according to Porter and discusses the differences between strategy and management as put in Porter’s, ‘What is Strategy’.Advertising We will write a custom case study sample on What is Strategy by Michael Porter specifically for you for only $16.05 $11/page Learn More Porter (62) defines strategy in terms of operational effectiveness. According to Porter, in this case strategy goes hand in hand with operational effectiveness, where the latter is mainly about the doing same things in a better manner than the rivals. Porter goes ahead to define strategy as a matter of difference in the performance of business activities. In this real m, he has exemplified the aspect of strategy by using organizations that have succeeded in strategic positioning, such as South West airline and IKEA. Using this perspective, strategic competition has been perceived as coming up with novel positions that will be able to attract customers in a better manner than that of the rivals. Strategy according to Porter is mainly based on the needs of the customer and issues that will satisfy the needs of the customer. In the article, Porter has defined strategy as the act of creating positions that are unique and valuable through the use of varying activities (Porter, 68). From this argument, it has been made clear that the essence of strategy is all based on creation of a position that is different from that of the rivals such that, one gets a competitive advantage. Creation of the position is not a straightforward guarantee to competitive advantage over other rivals (Porter, 68). In such a case, it is necessary to have tradeoffs, where a bu siness can choose to shrug off some factors and insist on others. Tradeoffs, as a strategy, may seem like a limit to what a company is offering but they tend to increase the strategic positioning of the particular company. In this realm, strategy has thus been defined as the use of tradeoffs in competition by sacrificing some offers for others (70).Advertising Looking for case study on business economics?

In this realm, activities should be in such a manner that they are consistent with each other, reinforce each other, and are able to optimize the efforts of the company in achieving its objectives. When this happens, the organizational structure will enjoy competitive advantage in a sustainable manner. According to the discussion laid out by Porter, strategy is an aspect of management. It is a core part of management (Porter, 77). The management of an organization is responsible for laying down strategy. There is a difference between the two terms, such as laid in the facet of operational effectiveness. The latter is an essential integral of management but does not stand out to be a strategy. Strategy is thus a management principle, where, the position of a company can be defined, tradeoffs made and a fit amongst activities forged. This aids the organization or the company in maintaining of a competitive and sustainable advantage. Managers are responsible for maintaining strategy for various organizational needs. They are responsible for making decisions on what to do and what not to do in the organization, as dictated by the set strategies. Reference Porter, M. (1996). What is Strategy?
