3)a) The distinctive test for Copper ions is when ammonia solution is added to the copper ions solution it turns light blue and little excess ammonia is added deep blue color which is the most distinctive test and aluminon and ammonia test is not effective as there is not much effect.
b) aluminon and ammonia regaent is suitable for distinctive test of Al+3 ions. After treating with ammonia Al(OH)3 precipitate is formed and later when aluminon is added it turns red precipitate with colorless solution which is used to detect the presence of aluminium ions.
