Chapter 13, Problem 13.150P

(a)

Interpretation Introduction

Interpretation:

The solubility of ${\text{SO}}_2$ is to be determined.

Concept introduction:

Henry’s law gives the quantitative relationship between the pressure of the gas and its solubility. It states that the amount of gas dissolved in a liquid is proportional to the partial pressure of the gas. Higher the partial pressure of the gas, more will be its solubility and vice-versa.

The formula to calculate the solubility of gases according to Henry’s law is as follows:

$S_{\text{gas}}=k_{\text{H}}\times P_{\text{gas}}$ (1)

Here, $S_{\text{gas}}$ is the solubility of the gas.

$k_{\text{H}}$ is Henry’s constant.

$P_{\text{gas}}$ is the partial pressure of the gas.

(b)

Interpretation Introduction

Interpretation:

The reason for the use of basic solutions in scrubbers is to be determined.

Concept introduction:

The solution is a homogeneous mixture of two or more substances. It can exist in any of the phases. Saltwater, rubbing alcohol, bleach, and air are some examples of solutions. It has two components: solute and solvent. The solute is the substance that is present in smaller quantity and gets itself dissolved in the other substance. The solvent is the substance that is present in a larger amount and it dissolves solute in itself.

The characteristics of the solution are as follows:

1. It is a homogeneous mixture of two or more substances.

2. The particles of solute can never be seen by the naked eye.

3. It does not allow the light beam to scatter.

4. It is stable.

5. The components of the solution cannot be separated by filtration.

6. It is composed of one phase only.
