Answer:
addition of aqueous hydrochloric acid
Explanation:
The solubility of copper (ll) hydroxide in water is negligible. This implies that the substance is only slightly soluble in water.
However, the addition of aqueous hydrochloric acid leads to the following reaction;
Cu(OH)2 + 2HCl ---------> CuCl2 + 2H2O
Copper II chloride is soluble in water hence the crystals dissolve when stirred. and the molar solubility increases.

Answer:
HCN, weak acid
H⁺, Br⁻, strong acid
Explanation:
Hydrocyanic acid is a weak acid, according to the following equation.
HCN(aq) ⇄ H⁺(aq) + CN⁻(aq)
Thus, it should be written in the undissociated form (HCN).
Hydrobromic acid is a strong acid, according to the following equation.
HBr(aq) ⇒ H⁺(aq) + Br⁻(aq)
Thus, it should be written in the ionic form (H⁺, Br⁻).
