उत्तर
The metallic hydroxide which forms a deep inky blue solution with excess ammonium hydroxide solution is Cu(OH)2.
Explanation:
The pale blue Cu(OH)2 precipitate dissolves in excess of ammonium hydroxide derived from tetraamine copper sulphate.
\[\ce{Cu(OH)2 + (NH4)2SO4 + 2NH4OH -> [Cu(NH3)4]SO4 + 4H2O}\]
