Answer:

(A) no reaction

Explanation:

in first question no reaction will take place as copper reacts with concentrated sulphuric acid to form hydrogen

  • (B)Iron in copper sulphate gives rise to iron sulphate and copper is evolved

Hello Friend,

I hope You understand this

Answer:

(i) No reaction occurs when dilute sulphuric acid is poured on a copper plate. However, when concentrated sulphuric acid is poured on a copper plate, hydrogen gas evolves along with the formation of blue coloured copper sulphate crystals. The chemical reaction for the reaction between concentrated sulfuric acid and copper is:

 Cu + H_{2}SO_{4} (conc.)  → CuSO_{4} + H_{2}

ii) Iron being more reactive displaces copper from copper sulphate. In this reaction, the blue colour of copper sulphate fades and there is a deposition of copper on the iron nail.

Fe + CuSO_{4} →  FeSO_{4}  + Cu
