Question
Water is added to a group chloride precipitate and heated. The precipitate seems unaffected by heating. The supernatant is separated from the precipitate while hot and treated with K2CrO4 (aq) but no precipitate forms. The white precipitate remaining from the first step is treated with NH3 (aq) and turns a grey/black color. When the ammoniacal supernatant is acidified with nitric acid, a white precipitate forms. Sort the statements from the paragraph above into bins indicating what information the statement provided.

Water is added to a group chloride precipitate and heated : Indicates possible presence of Hg2^2+ ans Ag+
The precipitate seems unaffected by heating. : indicates absence of lead
The supernatant is separated from the precipitate while hot and treated with K2CrO4 (aq) but no precipitate forms.: does not indicate presence or absence of any ion
The white precipitate remaining from the first step is treated with NH3 (aq) and turns a grey/black color : confirms presence of Hg2^2+
When the ammoniacal supernatant is acidified with nitric acid, a white precipitate forms. : Indicates presence of Ag+ ion
