Question

A salt of binary acid $H_{2}S$ is $MS$. Then the valency of metal $M$ is 2.

• A. True
• B. False

Answer 1

The correct option is A True

Given: Salt of binary acid $H_{2}S$ is $MS$

Valency of sulphur in $H_{2}S$ is $-2$

$\therefore$ It combines with $M^{2+}$ to form $MS$. So valency of metal is $2$ .
