Why can't the Solvay Process be used to manufacture potassium carbonate?
Options
- APotassium hydrogen carbonate is too insoluble.
- BPotassium hydrogen carbonate is too soluble.
- CPotassium chloride is not available.
- DPotassium hydroxide is too expensive.
Correct answer
B. Potassium hydrogen carbonate is too soluble.
Step-by-step solution
The Solvay Process cannot be extended to the manufacture of potassium carbonate because potassium hydrogencarbonate is too soluble to be precipitated by the addition of ammonium hydrogen carbonate to a saturated solution of potassium chloride.
