what do you observe when ammonium Hydroxide is added in excess to copper sulphate solution? what is the colour change​

Answer 1

Answer:

When ammonium hydroxide is added in the solution of copper sulfate drop-wise, a pale blue precipitate of copper hydroxide is obtained. The equation for this follows: When ammonium hydroxide is added in excess, the precipitate dissolves and gives a deep blue solution of tetraammine copper (II) sulfate.
