Chapter 13, Problem 13.127SP

Interpretation Introduction

Interpretation:

The reason for the boiling point of a solution prepared by dissolving 71 g of ${\text{Na}}_{\text{2}}{\text{SO}}_{\text{4}}$ in 1.000 kg of water to be 100.8°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 at which is exerted by vapor on the liquid surface in a closed system when the system is in thermodynamic equilibrium.
