Chapter 13, Problem 66QAP

Interpretation Introduction

Interpretation:

The reason for the gas to become saturated with water vapor when collecting small samples of gases in laboratory by bubbling gas into a flask containing water should be explained. And how we must take the presence of water vapor into account when calculating the properties of the gas sample, should be explained.

Concept Introduction:

According to Dalton’s Law of Partial pressures, the total pressure of mixture of gases non-reactive in nature is equal to the sum of partial pressure of each gas. This is mathematically represented as follows:

${\text{P}}_{\text{T}}={\text{P}}_{\text{A}}+{\text{P}}_{\text{B}}+{\text{P}}_{\text{C}}$

Here, ${\text{P}}_{\text{T}}$ is total pressure of mixture of gas A, B and C.
