Current Question (ID: 18087)

Question:

$\text{A solution that has the highest boiling point among the following is:}$

Options:

1. $1.0 \text{ M NaOH}$
2. $1.0 \text{ M Na}_2\text{SO}_4$
3. $1.0 \text{ M NH}_4\text{NO}_3$
4. $1.0 \text{ M KNO}_3$

Solution:

$\text{Hint: Boiling point of solution directly proportional to the van't Hoff factor value}$ $\text{Explanation:}$ $\text{As we know greater the value of van't Hoff factor higher will be the elevation in boiling point and hence higher will be the boiling point of the solution. The values are as follows:}$ $\begin{array}{cc} \text{Solution} & \text{van't Hoff factor (i)} \\ 1.0 \text{ M NaOH} & 2 \\ 1.0 \text{ M Na}_2\text{SO}_4 & 3 \\ 1.0 \text{ M NH}_4\text{NO}_3 & 2 \\ 1.0 \text{ M KNO}_3 & 2 \end{array}$ $\text{Hence, 1.0 M Na}_2\text{SO}_4 \text{ has the highest value of the boiling point.}$
