Chapter 13, Problem 51E, Determine from the following molecular view of a hydrofluoric acid (HF) solution whether HF is a

Interpretation Introduction

Interpretation:

Hydrofluoric acid is a strong or weak acid is to be determined from the given molecular view.

Concept Introduction:

A strong acid or base completely dissociates into its ions in an aqueous solution.

A weak acid or base does not dissociate completely into its ions in an aqueous solution.

Explanation of Solution

The acids that completely dissociate into their ions are strong acids.

The general reaction of dissociation of an acid, HA, in an aqueous solution is shown below.

HA+ H2O A(aq)+ H3O(aq)+

The concentration of A and H3O+ ions is the deciding factors, whether the acid is strong or weak.

In the figure given, the 2 green balls represent 2F, the green and white balls together represent 3HF and the two white balls with one red ball represent H3O+
