3. Indicators
 Generally three types of indicators we use in various
titrations-
◦ Internal Indicators
 Eg. Diphenyl benzidine violet
◦ Self Indicators
 Eg. Potassium Permanganate
◦ External Indicators
 Eg. Potassium ferricyanide

4. Redox Titrations
 Redox titrations are based on the Oxidation-Reduction
reactions, these reactions are the chemical processes in
which a change in the valency of reacting elements or
ions takes place.
 Types of Redox Titrations-
Various types of redox titrations are available in analytical
techniques-

5. Types;
 Cerimetry
 Iodimetry
 Iodometry
 Bromometry
 Dichrometry
 Titration with Potassium iodate
