Copper forms 2 different compounds with the chloride ion, CuCl & CuCl2. In writing their names, how do we distinguish between them?

CuCl2 is yellowish brown (powder) in color, soluble in H2O, alcohol, and ammonium chloride. It is used in dying copper, silver, and gold. CuCl is a green (powder) in color such as the resin in copper, it is insoluble in H2O. Anymore questions please email me.

You need to write the compound based on which oxidation state the copper is in. Copper is commonly found in +1 and +2 states which explains why it forms two different compounds with chlorine. You would write it like thus: Cu(I)Cl (With the I being a roman numeral 1) and Cu(II)Cl2 (With the 2 being roman numeral for 2)
