MP Board · Class 12 · Chemistry · SolutionsWhich of the following aqueous solutions should have the highest boiling point?
Boiling point elevation is a colligative property directly proportional to the van't Hoff factor ($i$) and molality. $1\text{ M NaOH}$ dissociates into 2 ions ($i=2$), $1\text{ M Na}_2\text{SO}_4$ into 3 ions ($i=3$), $1\text{ M NH}_4\text{NO}_3$ into 2 ions ($i=2$), and $1\text{ M KNO}_3$ into 2 ions ($i=2$). Therefore, $\text{Na}_2\text{SO}_4$ gives the highest number of particles, leading to the highest boiling point.
