Question

cu+h2so4=cuso4+ h2
How is this possible if copper is below h2 in reactivity series? ​

Answer 1

Answer:

Copper doesn't react with sulphuric acid because it lies below in the reactivity series and also its reduction potential is higher than that of hydrogen (concept of class 11th).

But when copper is heated with conc. sulphuric acid, then the acid get reduced to sulphur dioxide.

The reaction is :

Cu + H₂SO₄ → CuSO₄ + SO₂ + H₂O
