A certain compound (A) is  used in the laboratory for analysis, its aqueous solution gives the following reactions:  a. On addition to copper sulphate, a brown precipitate is obtained which turns white on addition of excess of the `Na_(2)S_(2)O_(3)` solution.  b. On addition to the `Ag^(o+)` ion solution, a yellow curdy precipitate is obtained which is insoluble in ammonium hydroxide. Identify (A) and give equations for the reactions at steps (a) and (b).
