Answer 1

Answer:

When concentrated ammonia solution(ammonium hydroxide) is added to a clear, light blue, aqueous solution of copper(II) chloride, a powdery, light blue precipitate ofcopper(II) hydroxide forms. Further addition of ammonia causes the copper ion to go back into solution as a deep blue ammoniacomplex.

Explanation:

Copper(II) ion reacts with stoichiometric quantities of aqueous ammonia to precipitate light blue Cu(OH)2. Some basic salts may also form.

Cu+2(aq)+2NH3(aq)+3H2O(l)↽−−⇀Cu(OH)2(s)+2NH+4(aq)
