Question

Chemical formula of metal sulfate is $MS{O}_4$. What will be the formula of its chloride?

• A. $MC{l}_2$
• B. $MC{l}_4$
• C. $M_{2}Cl$
• D. $MCl$

Answer 1

The correct option is A $MC{l}_2$

We know that, valency of sulfate is $-2$.
From the given formula of metal sulfate, valency of metal comes out to be $+2$.
We know, valency of chlorine is $-1$. So, formula of metal chloride becomes $MC{l}_2$.
