Question

The valency of metal whose sulphate is $MS{O}_4$ is $2$.

• A. True
• B. False

Answer 1

The correct option is A True

Valency is defined as number of electrons present in valence shell which are being lost, gained or shared with other atoms to form molecules and gain stability.

Valency of sulphate ion i.e. $S{O}_4$ is $-2$

(Refer to Image)

Hence, metal which combines with it should have $+2$ valency to accept $2$ electrons from sulphate ion.
