Among the following, the correct statement is
Among the following, the correct statement is
Show Hint
The solubility of salts in water typically increases as the ionic radius of the cation increases, reducing the lattice energy.
Updated On: Dec 11, 2025
- The density follows the order, Cs$^+$>Rb$^+$>Li$^+$>Na$^+$
- The solubility in water follows the order, Cs$_2$CO$_3$>K$_2$CO$_3$>Na$_2$CO$_3$>Li$_2$CO$_3$
- The first ionization potential follows the order, Li$^+$>K$^+$>Na$^+$>Cs$^+$
- The melting point follows the order, MgCl$_2$>BeCl$_2$>CaCl$_2$>SrCl$_2$

The Correct Option is B
Solution and Explanation
Step 1: Analyzing the order of solubility.
The solubility of alkali metal carbonates in water increases as the size of the cation increases. Larger cations like Cs$^+$ and K$^+$ form weaker ionic bonds with the carbonate ion, making the compounds more soluble in water.
Step 2: Conclusion.
Thus, the correct order for solubility in water is Cs$_2$CO$_3$>K$_2$CO$_3$>Na$_2$CO$_3$>Li$_2$CO$_3$, corresponding to option (B).
