Chapter 6, Problem 6.81P

Interpretation Introduction

(a)

Interpretation:

The fraction of KOH in the feed that is crystallized is to be calculated.

Concept introduction:

The neutralization reaction of an acid $\left(\text{AH}\right)$ and a base $\left(\text{BOH}\right)$ to given salt $\left(\text{AB}\right)$ and water is

$\begin{array}{l}\text{ AH}+\text{BOH}\to \text{AB}+{\text{H}}_2\text{O}\\ \text{Acid Base Salt Water}\end{array}$

Molarity is defined as the concentration of a solution in terms of its number of moles per u nit volume of the solution. Its formula is

$M\left(\text{mol/L}\right)=\frac{n}{V}$   ...... (1)

Here, $n$ is the moles of the solution and $V$ is its volume.

The process of formation of solid crystals which is highly organized structure of atoms or molecules is known as crystallization.

Interpretation Introduction

(b)

Interpretation:

Reconsideration of the sample of mother liquor using the given solubility information is to be done.

Concept introduction:

The neutralization reaction of an acid $\left(\text{AH}\right)$ and a base $\left(\text{BOH}\right)$ to given salt $\left(\text{AB}\right)$ and water is

$\begin{array}{l}\text{ AH}+\text{BOH}\to \text{AB}+{\text{H}}_2\text{O}\\ \text{Acid Base Salt Water}\end{array}$

Here, $n$ is the moles of the solution and $V$ is its volume.

The process of formation of solid crystals which is highly organized structure of atoms or molecules is known as crystallization.

The ability of a solute to get dissolved in a solvent is known as solubility which is measured in the maximum amount of solute that can be dissolved in the solvent at equilibrium.
