Question

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

Answer 1

Answer:

1. When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper
2. When iron nail is dipped in Copper sulphate, it takes reaction between them and Copper sulphate changes its color from blue to light green.

Answer 2

(a) When dilute sulphuric acid is poured on a copper plate, no reaction takes place due to less reactivity of copper.

(b) When iron nails are placed in a copper sulphate solution, the blue colour of the sopper sulphate solution changes to green, due to the displacement of copper in copper sulphate by iron.

hope this helps you.
