316715 In qualitative analysis when \(\mathrm{H}_{2} \mathrm{~S}\) is passed through an aqueous solution of salt acidified with dil. \(\mathrm{HCl}\), a black precipitate is obtained. On boiling the precipitate with dil. \(\mathrm{HNO}_{3}\), it forms a solution of blue colour. Addition of excess of aqueous solution of ammonia to this solution gives

1 Deep blue precipitate of \(\mathrm{Cu}(\mathrm{OH})_{2}\)
2 Deep blue solution of \(\left[\mathrm{Cu}\left(\mathrm{NH}_{3}\right)_{4}\right]^{2+}\)
3 Deep blue solution of \(\mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}\)
4 Deep blue solution of \(\mathrm{Cu}(\mathrm{OH})_{2} \cdot \mathrm{Cu}\left(\mathrm{NO}_{3}\right)_{2}\)
