Chapter 10.5, Problem 3E

Interpretation Introduction

Interpretation:

  $\text{HBr}$ existsmainly as ${\text{H}}_3{\text{O}}^{+}$ and ${\mathrm{Br}}^{-}$ ” is to be confirmed by calculation of equilibrium constant.

Concept Introduction:

The calculate equilibrium constant is as follows:

  $K_{\text{eq}}=\frac{K_{\text{a}\left(\text{HA}\right)}}{K_{\text{a}\left(\text{HB}\right)}}$

Where,

• $K_{\text{a}\left(\text{HA}\right)}$ refers to dissociation constant of strong acid $\text{HA}$ .
• $K_{\text{a}\left(\text{HB}\right)}$ refers to dissociation constant of weaker acid $\text{HB}$ .
