The Solvay process relies on the precipitation of sodium bicarbonate ($NaHC{O}_3$) due to its low solubility. Potassium bicarbonate ($KHC{O}_3$), however, is highly soluble in water and does not precipitate. This prevents the separation required for the Solvay process to produce potassium carbonate ($K_{2}C{O}_3$).
