Question

A class teacher demonstrates the effect of impurities on the boiling point of water using the arrangement of apparatus as shown. What could be the probable thermometer readings recorded during the experiment?

• A. ${97}^o$C
• B. ${100}^o$C
• C. ${102}^o$C
• D. ${99}^o$C

Answer 1

The correct option is C ${102}^o$C

When impurities are added to pure water with boiling point ${100}^{o}C$ the boiling of point of water increases due to the increases in vanthoff factor.So,the boiling point will be greater than ${100}^{o}C$ as there's only one option showing greater than ${100}^o$.

So option $C$ is correct.
