Question

Give scientific reason for: Potassium hydrogen carbonate cannot be obtained by Solvay soda process.

Answer 1

Solvay process cannot be used to prepare potassium carbonate. This is because unlike sodium bicarbonate, potassium bicarbonate is fairly soluble in water and does not precipitate out.

Answer 2

It is not possible to make potassium hydrogen carbonate by the Solvay soda process.

This is primarily because Potassium hydrogen carbonate is soluble in water which means that it does not crystallize and as it is not in heavier form, it cannot be separated from water or extracted with the help of this process.
