Chapter 12, Problem 12.28P

Interpretation Introduction

Interpretation:

The displacement titration should be explained with example.

Concept introduction:

Displacement titration:

In the $\text{EDTA}$ titration, some metal ions are not have a good indicator so that time the second metal complex ${\text{MY}}^{\text{2-}}$ is added to the first metal (analyte) solution, the second metal is replaced in $\text{EDTA}$ complex by first metal ion.

The good indicator having liberated second metal ion titrate with $\text{EDTA}$ solution to give a result.

Here the displacement of metal ions are gives a result of the titration therefore, it is called as a displacement titration.
