Question

Assertion :- When zinc rod is dipped into aqueous solution of copper sulphate, the colour of

the solution changes.

Reason:- Zinc being more reactive displaces less reactive copper from its aqueous solution

resulting in the formation of zinc sulphate which is colourless.

(a) A (b) B

(c) C (d) D​

Answer 1

Answer:

The answer is :

(a) Both assertion and reason are correct and reason is the correct explanation of assertion.

Explanation:

Yes it's true that Zink rod will displace Copper from Copper Sulphate solution :

Zn + CuSO4 ---------> ZnSO4 + Cu

This is because Zn is more reactive than Cute as shown in the reactivity series and thus forms ZnSO4.
