Chapter 16, Problem 16.22QP

Interpretation Introduction

Interpretation: The concentration of hydroxide ions in a solution of $250\text{mL}$ $\text{Ca}{\left(\text{OH}\right)}_{\text{2}}$ is to be calculated.

Concept introduction: The potential of ${\text{H}}^{\text{+}}$ ions is called as $\text{pH}$ and the potential of ${\text{OH}}^{-}$ ions is called as $\text{pOH}$. Concentration of ions in a solution depends on the mole ratio between the cation and anions and the dissolved substance.

To determine: The concentration of hydroxide ions in a $250\text{mL}$ solution of $\text{Ca}{\left(\text{OH}\right)}_{\text{2}}$.
