Explain an unknown solution containing only group 1 cations forms a white precipitate, P1, upon addition of hydrochloric acid. Addition of hot water produces a clear solution, S1. Which cation(s) is (are) definitely present, which is (are) definitely absent, and which is (are) uncertain in P1 and S1 based on the evidence given? State balanced net ionic equations to demonstrate your reasoning.
