Question

The boiling point of 0.01 M aqueous solutions of sucrose, NaCl and CaCl₂ would be

(a) the same

(b) highest for sucrose solution

(c) highest for NaCl solution

(d) highest for CaCl₂ solution

Answer 1

Answer is : (d) highest for CaCl₂ solution

As boiling point is a colligative property, it depends only on the number of particles present in a solution.

Aqueous solution having more number of particles will have highest elevation in boiling point.

Thus, CaCl₂ will have highest boiling point.
