Question

If $HCl$ is added to a solution of $copper\left( {II} \right)hydroxide$ how does this affect the solubility of the copper salt?

Answer 1

In order to this question, to know the effect when $HCl$ is added to a solution of $copper\left( {II} \right)hydroxide$ , we should write the reaction of them, and check what happened with their products.

Complete step by step answer:
$Cu{(OH)_2}$ is quite insoluble in water.
$CuC{l_2}$ is quite soluble in water.
So, the reaction is:
$Cu{(OH)_2}(s) + 2HCl(aq) \to CuC{l_2}(aq) + 2{H_2}O(aq)$
In solution, the copper ion probably exists as ${[Cu{(O{H_2})_6}]^{2 + }}$ , a beautiful blue coloured species.
Hence, when $HCl$ is added to a solution of $copper\left( {II} \right)hydroxide$ , it should increase the concentration of copper in solution.

Note:
Copper is one of the alleged "respectable metals." Just like the honorable gases will be gases that don't promptly respond, the honorable metals don't promptly respond in a ton of cases. They incorporate different components, for example, gold, so this wonder isn't exceptional to copper using any and all means.
