Solution

The correct option is D
M₂(SO₄)₃

MN is a neutral compound. So the overall charge should be zero.

From the formula of metal nitride MN, we can find that the charge of M is 3+. How? We know the charge of nitride is 3-

Both balance each other to get MN. Also, we know that charge of sulphate is 2-

Symbol M $S O_{4}$

Valency 3+ 2-

Criss-crossing the valencies, we get $M_{2} (S O_{4})_{3}$

Therefore, the formula of the metal sulphate is $M_{2} (S O_{4})_{3}$ .
