Chapter 8, Problem 8.40P

Interpretation Introduction

Interpretation:

The diagram that better represents the solution of $\text{NaF}$ dissolved in water is to be identified and reason behind the choice should be explained. Also, whether the solution will conduct electricity or not should be determined.

Concept introduction:

An electrolyte may be defined as the ionic compound that on dissolution in polar solvents dissociates to produces cationic and anionic species. There are three kinds of electrolyte namely strong electrolyte, weak electrolyte, and non-electrolyte.

The strong electrolytes are those which on dissolution dissociates completely into its constituent ions however, the weak electrolytes are not completely dissociated. For example, sodium chloride and sulphuric acids are regarded as strong electrolytes while acetic acid is regarded as a weak electrolyte.

Benzene and urea that don not dissociate at all and are termed as non -electrolytes.
