The formula for the sulphate of a metal is MSO 4 . What is the formula for the chloride of that metal?

Question

Philoid · Accepted Answer

It is given that sulphate of a metal is MSO₄.

By applying criss cross method, we can know the valency of “M”:

Hence, the valency of “M” is +2

Now, formula for chloride of metal M:

Formula: MCl₂

Thus, the formula for the chloride of metal is MCl₂.
