List as many as possible. Thank you.
1. List an example of a solution or reagent for which precision is
very important. Why is this so?
2. List an example of a solution or reagent for which precision is
less critical. Why is this so?
Homework Answers
1. When recalculate the concentration of elemental particles of water in finding the hardness of water, very precision is required, because the values are very minute like mg/ml or ug/ml (ug = micro gram). And a very small change in these values has a great impact on hardness calculation
2. While conducting titrations we take volumes of acid or base, here we don't need much precision because 2-3 ml of volume also doesn't show much difference in the overall molarity of the solution.

In this exercise, you will use two reagent mixtures to test a variety of organic halides. The distinct differences in the factors affecting the SN2 and SN1 mechanisms make it possible to determine which mechanism is favored by a given compound. One reagent and solvent favors SN2 reactivity, the other SN1 reactivity. From the results of your tests, you will determine which mechanism, if either, is favored by a given compound. In your post-lab assignment, you will be required to...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
