The problem with your question is that "Copper chloride" is not a chemical formula; it is the name of a chemical compound. However, I understand what you are asking. The problem with the name "copper chloride" is that it is ambiguous. One must be able to write an unambiguous chemical formula from the compound's name and vice versa, but that cannot be done here since "copper chloride" can be either CuCl or CuCl2.

Oxidized copper exists either as Cu+1 or as Cu+2. In other words, the copper atom has lost either one or two electrons. "Chloride" is chlorine with a -1 formal charge, thus it takes either one or two chloride ions to create [the neutral compound] copper chloride.

For metal ions, the name of the ion with the highest oxidation state has the suffix "-ic" and the ion with the lower oxidation state possesses the suffix "-ous." That means that copper chloride is actually either cupric chloride, CuCl2, or it is cuprous chloride, or CuCl.

What is wrong with this chemical formula CaCl2?

The chemical formula CaCl2 represents calcium chloride. It is correct as it shows that the compound contains one calcium atom and two chlorine atoms.


What is wrong with RbCl2?

The chemical formula RbCl2 is not correct because rubidium chloride (RbCl) typically only forms 1:1 stoichiometry where one rubidium ion is matched with one chloride ion. Therefore, the correct formula for rubidium chloride is RbCl.

What color is the flame when you burn copper II chloride?

A: If you put a piece of copper wire on any type of flame (most preferably cooking flames), then you would observe that they produce a green color in the flame. Sometimes, it might give youa blue tinge but if it doesn't, it doesn't mean that there's something wrong with the copper you're using.
