Addition of dil. Solution of `Ag NO_3 (aq)`, to excess of dil . Kl (aq). Gives :

Addition of HCl to an aqueous solution of Pb(NO_3)_2 gives a

Give appropriate reasons for the following : Addition of Cl_2 to Kl solution gives a brown colour but excess of Cl_2 turns it colourless

Gradual addition of KI solution to Bi(NO_3)_(3) solution initially produces a dark brown precipitate which dissolves in excess of KI to give a clear yellow solution. Write chemical equation for the above reactions.

In qualitative analysis when H_2S is passed through an aqueous solution of salt acidified with dil. HCl, a black precipitate is obtained. On boiling the precipitate with dil. HNO_3 , it forms a solution of blue colour. Addition of excess of aqueous solution of ammonia to this solution gives _______ .
