Na2CO3 can be manufactured by Solvay process but K2CO3 cannot be prepared because:
Correct answer: C. KHCO3 is more soluble than NaHCO3
- A. K2CO3 is more soluble
- B. K2CO3 is less soluble
- C. KHCO3 is more soluble than NaHCO3
- D. KHCO3 is less soluble than NaHCO3
Explanation
The Solvay process relies on the precipitation of bicarbonates. In the case of sodium, NaHCO3 is less soluble and precipitates out easily, allowing for the subsequent steps to produce Na2CO3. However, KHCO3 is more soluble and does not precipitate, making it unsuitable for the Solvay process to manufacture K2CO3. Thus, the correct answer is that KHCO3 is more soluble than NaHCO3. The other options incorrectly focus on the solubility of the carbonates themselves rather than the critical bicarbonate stage in the process.

About s-Block and p-Block Elements
The s and p blocks are studied through their valence-shell configurations, periodic trends and characteristic chemical properties. Work covers the reactions of Group I and Group II elements, the behaviour of Group IV elements, and how atomic size, ionization energy, electronegativity and metallic character change across periods and down groups.
