प्रश्न
What would you observe in the following cases:
Ammonium hydroxide is first added in a small quantity and then in excess to a solution of copper sulphate.
उत्तर
Adding a tiny amount of ammonium hydroxide produces blue precipitates. Excess ammonium hydroxide dissolves blue precipitates, yielding a vivid blue solution.
\[\ce{CuSO4 + 2NH4OH -> \underset{Blue ppt}{Cu(OH)2}↓ + (NH4)2SO4}\]
In excess
\[\ce{Cu(OH)2 + (NH4)2SO4 + 2NH4OH -> \underset{Deep Blue Solution}{[Cu(NH3)4]SO4} + 4H2O}\]
