Explanation The pOH scale is analogous to the pH scale. It is defined as the negative base 10 logarithm of hydroxide ions concentration present in the solution. Basicity of the solution is indicated by pOH. pOH = − log [ OH − ] …… (1) Also, pH is expressed as: pH = − log [ H 3 O + ] …… (2) The equilibrium expression for water is [ H 3 O + ] [ OH − ] = 1.0 × 10 − 14 Now, take negative logarithm of base-10 on both the sides as: − log ( [

Chapter 16, Problem 20QP

Interpretation Introduction

Interpretation:

The term pOH and its relationship with pH of the solution is to be determined.

Concept introduction:

pH is the measure of acidity of a solution and is dependent on the hydronium ion concentration and temperature of the solution.

The pOH scale is analogous to the pH scale.

The basicity of a solution is determined by the concentration of hydroxide ions present in the solution.
