Question

Why does potassium carbonate cannot be prepared by solvay process?

Answer 1

Answer:

The solubility of potassium carbonate is higher than the solubility of sodium carbonate. Hence, when carbon dioxide is passed through a concentrated $$KCl$$ solution contained ammonia, potassium carbonate is not precipitated. Hence, it cannot be prepared by the Solvay process.

Answer 2

• The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate. The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine and limestone.
