Chapter 16.1, Problem 4RQ

Interpretation Introduction

Interpretation:

The molecular-level view of an aqueous solution of the weak acid HF have to be drawn.

Concept Introduction:

All weakacids are weak electrolytes. They partially dissociate to give corresponding ions in the aqueous solution.Most of the molecules remain undissociated in the solution.

Explanation of Solution

HF is a weakelectrolyte. It partially dissociates to give H+ ion and F- ion in the solution. Most HF molecules remain intact in the solution. HF molecules partially dissociate in aqueous solution to give H+ ion and F- ion. So the aqueous solution of HF contains H+ ion, F- ion and undissociated HF.

  $\mathrm{HF}\rightleftharpoons H^{+}+F^{-}$

  

This is a molecular-level view of an aqueous solution of the weak acid HF.
