Question

What happens when:
a) Dilute sulphuric acid is poured on a copper plate?
(b) Iron nails are placed in a copper sulphate solution?
Write word equations of the reactions involved.​

Answer 1

Answer:

h2so4 + cu ------ cuso4 + h2

Fe+3 + cuso4 -------- Fe2(so4)3 + cu

Answer 2

Answer:

(a) When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper. ... Copper gets deposited on the iron nail and green solution is ferrous sulphate solution.

Cu + H2SO4 → CuSO4 + H2

(b)) When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper. ... Copper gets deposited on the iron nail and green solution is ferrous sulphate solution.

CuSO4 + Fe → FeSO4 + Cu
