Chapter 19, Problem 106A

Interpretation Introduction

Interpretation : The equation for $\text{pOH}$ of a solution is to be expressed.

Concept Introduction : The negative logarithm of the concentration of hydrogen ions is the pH of a solution. The formula of pH is given as

  $pH=-log\left[H^{+}\right]$

Answer to Problem 106A

The addition of hydrochloric acid shifts the equilibrium towards the left of the reaction.

Explanation of Solution

pOH stands for the potential of hydroxide ions.

It measures the acidity or basicity of any solution.

The pOH range lies between 0-14.

Since the sum of pH and pOH is equal to 14.

pOH is calculated by the formula:

  $pOH=-log\left[O{H}^{-}\right]$

pH gives the results of hydrogen ion while the pOH gives the results of hydroxide ion.
