Chapter 13, Problem 13.134SP

Interpretation Introduction

Interpretation:

The mass % of the aqueous solution of ${\text{CaCl}}_{\text{2}}$ needs to be determined, if theVan’t Hoff for ${\text{CaCl}}_{\text{2}}$ is 2.71 and T_f is -1.14°C.

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.
