Interpretation Introduction

Interpretation:

The hydroxide ion concentration ${\text{[OH}}^{\text{-}}\text{]}$ of the given solution has to be calculated.

Concept Information:

$pOH$ definition:

The $\text{pOH}$ of a solution is defined as the negative base-$10$ logarithm of the hydroxide ion ${\text{[OH}}^{\text{-}}\text{]}$ concentration. $\text{pOH}$ scale is analogous to pH scale.

$\text{pOH}\text{=}{\text{-log[OH}}^{\text{-}}\text{]}$

On rearranging, the concentration of hydroxide ion ${\text{[OH}}^{\text{-}}\text{]}$ can be calculated using $\text{pOH}$ as follows,

${\text{[OH}}^{\text{-}}\text{]}\text{=}{\text{10}}^{\text{-pOH}}$
