Question

valence of sulphate in copper (2)sulphate

Answer 1

Answer:

This means that the metal can have different valencies in different scenarios. So in copper sulphate or CuSO4, the valency of copper is +2 where as in Cu2O or copper oxide its valency is +1. The valency of copper in CuSo4 is 2(two).
