Can someone help with these questions:

a)Silver nitrate is added to a solution and a precipitate forms. This precipitate dissolves when concentrated ammonia is added. What anion was present in the original solution?
b)When dilute hydrochloric acid is added to a solution, a gas is evolved. If this gas is passed through a solution containing calcium hydroxide, a white precipitate forms. What anion was present in the original solution?
c)You are provided an aqueous solution which is blue. Addition of dilute hydrochloric acid produces a precipitate. The precipitate dissolves when the solution is heated to boiling. What two cations were in the original solution?

Thanks.

surely you would get a table of anions and colour precipitate, with whether it dissolves completely in conc. ammonia.

First post? So you apparently created an account just to write a unintelligible response to a post that's from five years ago?
