Question

Equal weights of m gram of the following substances were dissolved in equal amount of water . Which of these will have highest boiling points ?

Answer 1

1% CaCl2​ in water will have the maximum boiling point

Explanation:

Note: The question is incomplete. Please refer to the attached picture for the complete question.

We know that ΔTb or the boiling point elevation depends on the number of ions. So ΔTb increases with the increase in the number of ion. Also the boiling point is directly proportional to ΔTb. The more the boiling point elevation, the more will be the boiling point. So we can infer that more ions, more boiling point.

Hence 1% CaCl2​ in water will have the maximum boiling point.
