Potassium carbonate () cannot be prepared by the Solvay process. What is the primary reason for this — s Block Elements Chemistry Question

💡 Solution & Explanation

In the Solvay process, the key step is the precipitation of a sparingly soluble bicarbonate. When applied to potassium, the intermediate potassium bicarbonate ($KHCO_3$) is too soluble in water to precipitate out, preventing the reaction from proceeding to yield $K_2CO_3$.
