CuCl2 is an ionic compound with two elements, copper and chlorine. Chlorine is a halogen, part of Group XVII, and copper is a transition metal, of Group XI.
The Cu2+ from CuSO4 is displaced by the Na+ from NaCl and CuCl2 and Na2SO4 are formed.
In CuCl2, the oxidation state of copper (Cu) is +2, and the oxidation state of chlorine (Cl) is -1. This is because the overall charge of the compound is 0, and there are two chloride ions each with an oxidation state of -1 to balance the +2 charge of copper.
CuCl2(s) = Cu^2_(aq) + + 2Cl^-(aq) In solution the chloride anions )Cl^-) are colourless ; see also dissolved common salt (NaCl) So it must be the copper cations (Cu^2+) that gives the colour blue.
CuCl2 is the product.
