Chapter 15, Problem 94AE

Interpretation Introduction

Interpretation:

The $K_{\text{a}}$ value for the carboxylic acid group and the amino group in alanine is given. The ions that would predominate in a solution with $\left[{\text{H}}^{\text{+}}\right]=1.0\text{M}$ and in a solution with $\left[{\text{OH}}^{-}\right]=1.0\text{M}$ are to be stated.

Concept introduction:

The value of $\text{p}{K}_{\text{a}}$ is calculated by the formula, $\text{p}{K}_{\text{a}}=-\log \left(K_{\text{a}}\right)$

The $\text{pH}$ of a solution is calculated by the formula, $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

The $\text{pOH}$ of a solution is calculated by the formula, $\text{pOH}=-\log \left[{\text{OH}}^{-}\right]$
