Chapter 9.2, Problem 9.7QAP

Interpretation Introduction

Interpretation:

Elaborate the difference between $\text{KF}$ solution and $\text{HF}$ solution.

Concept introduction:

• Electrolytes can be further classified as strong electrolytes or weak electrolytes.

• For a strong electrolyte there is 100 % dissociation of the solute into ions but for a weak electrolyte the dissociation is not 100 %. A weak electrolyte is a compound that dissolves in water mostly as molecules, only a few molecules of the dissolved solute undergo dissociation and produce a small number of ions in solution.

Given:

$\text{KF}$ is a strong electrolyte and $\text{HF}$ is a weak electrolyte.
