2. For each of the following mixtures of substances, give the simplest reagent that could be used to separate the two substances into the ppt and a soln. Then, in a carefully written paragraph of two or three sentences, describe the observations and results of using this reagent. (For example: What is the appearance of the mixture before and after the reagent was used? As a result of using the reagent, which ion is in soln and which is in a ppt? What is the formula of the ppt? of the ion in soln?) a) A solid mixture of Cr(OH)3 and NiS. Reagent: b) A soln containing Mn2+ and Al+. Reagent: c) A soln containing Cu2+ and Zn2+. Reagent: (Hint: Use the overall Qualitative Analysis flowchart on page 22 of your manual to get started.)
