called r edox titrations. Y ou know that in acid-base titrations, indicators which are sensitive to pH change are employed to note the end point. Similarly, in redox titrations there is a change in oxidation potential of the system. The indicators used in redox reactions are sensitive to change in oxidation potential.

Titration Method Validation - United States Pharmacopeia

Using the assay of potassium bicarbonate by titration with hydrochloric acid (4) as an example, the expected impurity is potassium carbonate. The pK b values for potassium carbonate are at approximately 8.3 and 3.69, meaning it is possible to separate both species during an acid-base titration. To demonstrate this, pure potassium bicarbonate
