* Salts are ionic compounds formed by the reaction of an acid and a base.

* CuCl₂ is formed from the reaction of a strong acid (HCl) and a base (Cu(OH)₂):

2HCl (aq) + Cu(OH)₂ (s) → CuCl₂ (aq) + 2H₂O (l)

* Acids donate protons (H⁺ ions), while bases accept protons (OH⁻ ions).

* CuCl₂ itself does not donate or accept protons in solution.

Therefore, CuCl₂ is classified as a salt.
