Question

find the oxidation state of cu in cuc2o4​

Answer 1

Answer:

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. In this case, the oxygen atoms have -2 oxidation number, and sulphur +6, so (4 x -2) + 6 = -2 so the copper must be +2.
