Chapter 14, Problem 95A

Interpretation Introduction

Interpretation:

Colligative properties of solutions have to be defined.

Concept introduction:

Colligative properties are the properties of solutions, which entirely depend upon the number of solute particles (molecules or ions). Lowering of vapor pressure, osmotic pressure, elevation of boiling point and depression of freezing point are the examples of colligative properties.

Answer to Problem 95A

Colligative properties are the properties of solutions, which entirely depend upon the number of solute particles (molecules or ions) but does not depend on their nature.

Explanation of Solution

Colligative properties are entirely depend upon the number of solute particles but does not depend on their nature. These colligative properties are valid under the following conditions:

1. The solution must be very dilute.
2. The solute must be non-volatile
3. The solute must be non-electrolyte, i.e., the solute does not undergo any type of dissociation or association.
