+2 oxidation state for the Copper.
-1 for the Chloride
The oxidation state of copper in CuCl2 is +2. This is because chlorine typically has an oxidation state of -1 and the overall charge of the compound is neutral.
Simple halide ions always have an oxidation number of -1. Therefore, in this compound copper must have an oxidation number of +2 to achieve electrical neutrality for the compound.
+2 oxidation state
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 is a type II compound. In type II compounds, the cation can have multiple oxidation states, and the charge of the cation must be determined from the compound's formula. CuCl2 contains copper in the +2 oxidation state.
Copper can exist in two states of oxidation.The oxidation state of Cu in CuCl2 (cupric chloride) is +2 and that of Cl- is -1.However,the oxidation state of Cu in CuCl (cuprous chloride) is +1 and that of Cl- is -1.
Cupric chloride refers to the compound CuCl2, where copper has a +2 oxidation state. Cuprous chloride refers to the compound CuCl, where copper has a +1 oxidation state. This difference in oxidation state affects the chemical and physical properties of these compounds.
The formula for copper(I) chloride is CuCl, where copper has a +1 oxidation state. The formula for copper(II) chloride is CuCl2, where copper has a +2 oxidation state.
In CuCl, copper (Cu) has an oxidation number of +1 since chlorine (Cl) has an oxidation number of -1. This results in a balanced compound with a total charge of 0.
Copper can exist in two states of oxidation.The oxidation state of Cu in CuCl2 (cupric chloride) is +2 and that of Cl- is -1.However,the oxidation state of Cu in CuCl (cuprous chloride) is +1 and that of Cl- is -1.
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
With the oxidation state being II for copper. CuBr2
Copper (III) chloride. Note that this is theoretical compound copper does have a +3 oxidation stae in some complexes but does not from compounds such as CuCl3. The only halides known are +1 oxdtn state:- CuCl, CuBr, CuI +2 oxdtn state : CuF2, CuCl2, CuBr2
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.

There are two different copper chloride compounds, due to the two possible 'oxidation state numbers' (+1 and +2):CuCl cuprous chloride, Cu(I) chloride, mono-valent Copper chlorideCuCl2 cupric chloride, Cu(II) chloride, bi-valent Copper chloride
+2 oxidation state
The oxidation state of the cupric ion in copper tartarate is +2. Copper (II) ion, or cupric ion, has an oxidation state of +2 due to the loss of 2 electrons. In the case of copper tartarate, the ligand (tartarate) does not affect the oxidation state of the central copper ion.
CuCl2
Copper II chloride (CuCl2) is an ionic compound because copper is a metal and chloride is a non-metal. Like all ionic compounds in aqueous solutions (i.e., dissolved in water), it conducts electricity.
