Chapter 16.3, Problem 1PPC

Interpretation Introduction

Interpretation:

The diagram thatrepresents the increase of the ${\text{B}}^{-}$ ions in the solution to $8$ is to be determined.

Concept introduction:

Any species $\text{AB}$, if undergoes self-ionization being a weak electrolyte, dissociates partially into its constituent ions $\left[{\text{A}}^{+}\right]$ and $\left[{\text{B}}^{-}\right]$. The equilibrium expression for auto-ionization of this species will be:

$K_{\text{eq}}=\left[{\text{A}}^{+}\right]\left[{\text{B}}^{-}\right]$ …… (1)

According to Le Chatelier’sprinciple, if there is any disturbance in the system at equilibrium, then the system tries to undo the effect by shifting the reaction equilibrium in the desired direction.
