Question

oxidation number of cu in cuso4​

Answer 1

Answer:

number of cu in cuso4 is +2

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 in a compound the sum of all the oxidation numbers must come to zero.
