Chapter 6, Problem 6.3YT

Interpretation Introduction

Interpretation:

The $\text{pKa}$ values for ${\text{HCl and H}}_{\text{3}}{\text{O}}^{+}$ in equation $\text{6}-\text{1}0$ are to be determined, and it is to be verified that $\text{HCl}$ is a stronger acid than ${\text{H}}_{\text{3}}{\text{O}}^{+}$.

Concept introduction:

The acid with more negative $\text{pKa}$ value is a stronger acid.

$\text{pKa}$ value of $\text{HCl}$ is $\text{-7}$, and $\text{pKa}$ value of ${\text{H}}_{\text{3}}{\text{O}}^{+}$ is $\text{-1}\text{.7}$.

Each difference of $\text{1}$ in $\text{pKa}$ values represents a factor of $\text{1}0$ difference in acid strength.
