Question

Potassium carbonate cannot be prepared by Solvay process because ____________.

Options

• K₂CO₃ is water soluble

• KHCO₃ does not decompose upon heating

• KHCO₃ is fairly soluble in water

• KHCO₃ is sparingly soluble in water

Answer 1

Potassium carbonate cannot be prepared by Solvay process because KHCO₃ is fairly soluble in water.

Explanation:

Because potassium bicarbonate (KHCO₃) is moderately soluble in water, it does not precipitate, whereas sodium bicarbonate (NaHCO₃), which is sparingly soluble in water, does. As a result, the Solvay method is utilised to make Na₂CO₃ but not K₂CO₃.
