Question

Potassium carbonate cannot be made by solvay process using potassium chloride in place of sodium chloride. why?

Answer 1

Because in the reaction they form precipitate which is not soluble and hence it is not used for this process.

Answer 2

Hey dear,

● Why can't potassium carbonate be prepared by solvay process ?
- The solvay process is used for industrial preparation of sodium carbonate (soda ash).
- In this process brine (sodium chloride) is converted into soda ash (sodium carbonate) which being insoluble precipitates out.
- If potassium chloride is used instead, potassium bicarbonate thus formed being highly soluble in water doesn't precipitate.
- Therefore, potassium carbonate is not prepared by solvay process.

Hope it helps...
