हिन्दीWhich of the following aqueous solution will exhibit highest boiling point?
Correct answer · Option 3
\( 0.01\text{M} \) \( \text{Na}_2\text{SO}_4 \)
Explanation
Boiling point elevation \( \Delta T_b \propto i \cdot m \). For \( 0.01\text{M}\text{ Na}_2\text{SO}_4 \), \( i = 3 \), giving effective concentration \( = 0.03\text{M} \), which is the highest among all options.
