Question

What is valence of Copper Chloride

Answer 1

Answer:

Being a transition metal, copper exhibits variable valencies of 1 and 2. Copper forms two types of chlorides - cuprous chloride, Cu2Cl2, and cupric chloride, CuCl2. In the Cu2Cl2, the metal and chlorine atoms are 1:1 ratio and in CuCl2 the atomic ratio is 1:2. Therefore, the valencies of copper are 1 and 2
