Question

The Solvay (Ammonia-Soda) process is a highly efficient industrial method for the manufacture of Sodium Carbonate ($Na_2CO_3$). However, Potassium Carbonate ($K_2CO_3$) cannot be manufactured using this exact same process. Why?

Prashant Kotian · Accepted Answer

Correct answer: C. The Solvay process relies on the precipitation of a sparingly soluble intermediate, , which is then filtered and calcined. When applied to potassium, the intermediate is too highly soluble in water and will not precipitate out, rendering the process useless.
