For this exercise, let's say that you begin with an aqueous mixture containing the following compounds: Ba(NO3)2, Mg(NO3)2, and AgNO3 You also have separate solutions, one of each: K2SO4 (aq), KCI (aq), and KOH(aq) Let's call these the challenge reagents. Your task is to propose a step-by-step procedure for sequentially separating the...

You have a solution that may contain up to two of the following 4 cations: Ag+, Pb2+, Cu2+, Ni2+. The initial solution is clear and blue. Upon adding NaCl, a white precipitate forms. You centrifuge and decant the solution, and heat the portion where the white precipitate is. Heating causes the white precipitate to dissolve. To the supernatant liquid, which is still blue, you add ammonia, resulting in a deep blue color. Which cations are present?

1. Write the chemical formulas for all the barium salts that can be formed in Part 1 Part 1A: Solubility of barium salts under neutral conditions 1. Using a clean disposable pipet, transfer 1 mL of Co-anion solution to a clean test tube and label the test as "Co?- neutral". Repeat this for the remaining anion solutions S0?-?,P03-?, NO3",C1-7,7- 'so that you will have six test tubes with six unique anion solutions. Use a different pipet for each anion solution,...
