Expert Answer:
The oxidising property of concentrated sulphuric acid is due to the fact that on thermal decomposition, it yields nascent oxygen [O].
H2SO4 → H2O + SO2 + [O]
Nascent oxygen oxidises non-metals, metals and inorganic compounds.
Hence, copper can get oxidised on reaction with H2SO4.
Cu + 2H2SO4 → CuSO4 + 2H2O + SO2↑
Thus, copper sulphate can be formed from reaction of copper and sulphuric acid.
