A chemist prepares five beakers with exactly 1.0 M of the specified salt dissolved in water. The solutions are combined in a series for four steps. In each reaction assume complete formation of any solid products (ignore equilibrium). Be careful as some reactions may only require half the available ion.
22. Step 1: The barium chloride solution is poured into the lead(II) nitrate solution. What (if any) precipitate forms?
23. Step 2: Sodium hydroxide solution is poured into the aqueous part of the Step 1 mixture. What (if any) precipitate forms?
24. Step 3: Potassium sulfate solution is poured into the aqueous part of the Step 2 mixture. What (if any) precipitate forms?
25. Step 4: Copper(II) acetate solution is poured into the aqueous part of the Step 3 mixture. What (if any) precipitate forms?
26. At the very end, after all the solutions are combined and all precipitates have formed, how many cation species and how many anion species remain in the solution?

Experiment 8 Double Replacement Reactions Background: Some reactions have the net effect of causing the cation of each reactant to trade places, forming a compound with the other anion. These reactions are known as double replacement reactions. In the example below (unbalanced equation), the barium and sodium cations switch places so that barium forms a product with sulfate while sodium forms a product with chloride. Note that the formula of each product is determined by the charges of the ions,...
