Chapter 16, Problem 16.5P

Interpretation Introduction

Interpretation:

The solution with higher pH and largest dissociation constant should be identified.

Concept introduction:
Hydrofluoric acid is a weak acid and dissociates partially in the solution as follows:

  $\text{HF} \rightleftarrows {\text{H}}^{+}+{\text{ F}}^{-}$

On dissociation, hydrofluoric acid gives proton and fluoride ion.
