Answer 2

Complete question:

Sodium and potassium are placed in the same group of modern periodic

table. If the molecular formula of sodium sulphate is Na2SO4, then decide

the molecular formula of potassium sulphate. Give reason for your answer.​

Complete Answer:

The molecular formula of potassium sulphate is K2SO4.

- The elements with similar chemical properties are placed in the same group of the modern periodic table.

- Thus the valency of both sodium and potassium is the same, i.e., +1.

- So, they will react to form similar sulphates.

- Hence, we just replace Na with K in the formula of sodium sulphate to get K2SO4 as the formula of potassium sulphate.
