Question

Ammonium hydroxide precipitates hydroxides of which metals

Answer 1

Ammonium hydroxides precipitates on Copper

The reaction of Ammonium hydroxide with Cooper is as follows

2NH4 OH (aq) + CuCl2 (aq) → 2NH4 Cl (aq) + Cu(OH)2 (s)

Ammonium hydroxide reacts with copper(II) chloride producing solid copper(II) hydroxide, which is a precipitate (a solid), and ammonium chloride, which is a salt. A salt is an inorganic solid compound formed between oppositely charged ions.
