Select correct statement(s) :
Options:(select one or more)
Answer:
A, B, C
Solution:
A. NaHCO₃ exists in solid state, while LiHCO₃ exists in water. This is correct. Lithium bicarbonate is unstable and exists only in aqueous solution.
B. K₂CO₃ cannot be prepared using the Solvay process. This is correct because potassium bicarbonate is too soluble to precipitate.
C. Low solubility of LiF is due to high lattice energy, and low solubility of CsI is due to smaller hydration energy. This is correct.
D. Na₂CO₃ is prepared using the Solvay process, not the Castner-Kellner cell. The Castner-Kellner cell is used for NaOH and Cl₂ production.
