Question

Sodium carbonate can be manufactured by solvay's process but potassium carbonate cannot be prepared because:

• A. is more soluble
• B. K₂CO₃ is less soluble
• C. KHCO₃ is more soluble than NaHCO₃
• D. KHCO₃ is less soluble than NaHCO₃

Answer 1

The correct option is C

KHCO₃ is more soluble than NaHCO₃

Sodium carbonate can be manufactured by solvay's process but potassium carbonate cannot be prepared because KHCO3 is more soluble than NaHCO3.Sodium bicarbonate when heated we get sodium carbonate.

$NaHC{O}_3\to N{a}_{2}C{O}_3+H_{2}O+C{O}_2$

But where as we cannot do the same in case of potassium bicarbonate as it is more soluble.
