Chapter 7, Problem 2ASA

Interpretation Introduction

(a)

Interpretation:

The number of moles of ${\text{Cl}}^{-}$ ion present in the sample is to be calculated.

Concept introduction:

Moles of the chloride ion are equal to the moles of the silver ion added in the system in the titration of the chloride ion sample with silver nitrate. Numbers of moles are defined as the given mass of the species divided by the molar mass of that species.

Interpretation Introduction

(b)

Interpretation:

The concentration of the chloride ion in the diluted solution is to be determined.

Concept introduction:

The concentration of the chloride ion present in the unknown sample is determined by the argentometric titration. The chloride ion sample is titrated with the silver nitrate solution to calculate the concentration of the chloride ion.
