An inorganic compound (A) is a Lewis acid an d light yellow in colour. It fumes in moist air. The intensity of fumes further increase when a rod dipped in NH_(4)OH is brough near it. The aciedic solution of the compound does not give andy precipitate on passing H_(2)S gas. However, it gives a white precipitate on adding NH_(4)OH solution in the presence of NH_(4)Cl and the white precipitate dissovles on adding NaOH in excess. The intensity of fumes increases due to the formation of

    When NaOH is added to CuSO_(4) solution, a pale blue precipitate is obtained. On adding aqueous ammonia solution, the precipitate dissolves to give a deep blue solution. If the solution is made acidic with dilute nitric acid, the solution turns pale blue again. Explain each step with the reaction taking place.
