Solvay process is not used for the manufacture of potassium carbonate, because of the reason that potassium bicarbonate ?
Correct answer: B. Is soluble in ammonium chloride and potassium chloride solution
- A. Is prone to thermal decomposition
- B. Is soluble in ammonium chloride and potassium chloride solution
- C. Has high water solubility and is unstable
- D. All A , B. and C.
Explanation
The Solvay process depends on precipitating a sparingly soluble bicarbonate, but potassium bicarbonate remains soluble in the ammonium chloride and potassium chloride solution. It therefore cannot be separated effectively by the usual Solvay precipitation step.
