Chapter 19, Problem 19.109P

Interpretation Introduction

Interpretation:

The number of pounds per hour of sodium acetate trihydrate must be added to maintain $\text{pH}$5 or greater is to be calculated.

Concept introduction:

The strong acids have lower $\text{pH}$ value but they have a higher concentration of $\left[{\text{H}}_3{\text{O}}^{+}\right]$.

The buffer solution is the type of solution that consists of a weak acid and its conjugate base.

The expression to calculate the concentration of solute is as follows:

  $\text{Concentration of solute}=\frac{\left(\text{Moles of solute}\right)}{\left(\text{Volume of solution}\right)}$

The expression to calculate $\text{pH}$ of the buffer solution is given as follows:

  $\text{pH}={\text{pK}}_{\text{a}}+\log \left[\frac{\text{Conjugate base}}{\text{Acid}}\right]$        (1)
