Question

The formula of the chloride of metal is MCl2. what will be the formula of its sulphate? ​

Answer 1

Molecular Formula: AlClHO5S-

Answer 2

The formula of sulphate with the given metal is given and explained below.

• If there are two chloride ions bonded with the given metal 'M' then the possible valency of the metal should be 2+ and the known valency of the chloride is 1-.
• In a similar case, sulphate has a valency of 2-, so the formula of the metal with its sulphate will be $MSO_{4}$ because the metal here also has a valency of 2+.
• The example can be given as the metals having a valency of 2+. The possible metals are magnesium (Mg) or calcium (Ca).
• The formula with sulphate will be $MgSO_{4}$ and $CaSO_{4}$.
