Chapter 17, Problem 17.87QP

Interpretation Introduction

Interpretation:

The $\text{pH}$ value of saturated aluminium hydroxide ${\text{Al(OH)}}_{\text{3}}$ solution has to be calculated.

Concept introduction:

• The $\text{pH}$ of a solution is a figure that expresses the acidity or the alkalinity of a given solution.
• $\text{pH}$ is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.

$\text{pH}\text{=}{\text{-log[H}}_{\text{3}}{\text{O}}^{\text{+}}\text{]}$

• $pOH$ is the negative base-10 logarithm of the hydroxide ion ${\text{[OH}}^{\text{-}}\text{]}$ concentration.

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

• Relationship between $\text{pH}$ and $\text{pOH}$ is that $\text{pH}\text{+}\text{pOH}\text{=}\text{14}$.
