Problem
Equal volumes of 0.10 M potassium nitrate solution and 0.10 M calcium chloride solution are thoroughly mixed at 25 °C. No other substances are present.
(a) Describe whether a precipitate is expected to form when the two solutions are mixed. Justify your prediction using solubility principles rather than numerical calculations.
(b) Identify any spectator ions present after the mixing process is complete, and explain why they are classified as spectator ions.
(c) For the ions that remain in solution, use the solubility rules to explain why they do not form an insoluble compound under these conditions.
