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

Explanation:

Copper does not react with dilute sulphuric acid. ... Answer: When iron nails are placed in copper sulphate solution, the blue colour of copper solution is replaced by a light green colour. This happens because iron; being more reactive than copper; displaces copper from copper sulphate and makes iron sulphate.

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.

(b) When an iron nail is dipped in copper sulphate solution, a brown coating of copper is formed on the surface of iron and the colour of copper sulphate solution changes from blue to light green.
