Question

When zinc granules are added to copper sulphate solution then solution becomes colourless.

• A. True
• B. False

Answer 1

The correct option is A

True

Zinc is more reactive than copper so when it is added to copper sulphate solution (blue colour) it displaces copper to form zinc sulphate solution which is colourless.It is a displacement reaction.

$Zn\left(s\right)+CuS{O}_4\left(aq\right)\to ZnS{O}_4\left(aq\right)+Cu\left(s\right)$
