Chapter 16.6, Problem 1PPC

Interpretation Introduction

Interpretation:

The two whole numbers between which the pOH of the solution would lie is to be determined, when the hydroxide ions concentration is given.

Concept introduction:

pOH is a measure of the basicity of a solution, which depends on the concentration of hydroxide ions and the temperature of the solution.

The formula to calculate the pOH of a solution is:

$\text{pOH}=-\text{log}\left[{\text{OH}}^{-}\right]$ …… (1)

If the hydroxide ion concentration liesbetween $1.0\times {10}^{-a}\text{ and }1.0\times {10}^{-b}$, the pOH will lie between the whole numbers $a\text{ and }b$.
