Interpretation Introduction

Interpretation:

The reason for the difference in change in temperature when 100 mL of 9 M ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ at 0°C is added to 100 mL of liquid water and when the same ${\text{H}}_{\text{2}}{\text{SO}}_{\text{4}}$ is added to 100 g of solid ice at 0 °C needs to be explained.

Concept introduction:

Colligative properties are the properties that depend on the number of particles present in the solution. Elevation in boiling point, depression in freezing point, lowering in vapor pressure and osmotic pressure are some common examples of colligative properties. Vapor pressure is the pressure that is exerted by vapor on the liquid surface in a closed system when the system is in thermodynamic equilibrium. The temperature at which the vapor pressure becomes equal to the atmospheric pressure is called as boiling point.
