What is the charge of the metal ion in CuSO4?
Feb 18,2024
+2 ChargeThe proper name for CuSO4 is copper(II) sulphate - the Roman numerals denote the oxidation state for any atom which has variable oxidation states, such as transition metals.
We could start from a knowledge that the sulphate ion has a 2- charge, so the copper ion must have a 2+ charge and hence a +2 oxidation number. We could substitute in the oxidation numbers of the sulphur and oxygen atoms, and apply the rule that:
The Charge On The Compound is 0.
Oxidation Number Of Oxygen is -2.
Oxidation Number Of Sulphur is +6.
So (4 x -2) + 6 = -2 so the copper must be +2.
Oxidation Number Of Cu in Copper Sulphate is +2.
