What is redox titration? A TITRATION WHICH DEALS WITH A . REACTION INVOLVING OXIDATION AND . REDUCTION OF CERTAIN CHEMICAL . SPECIES. What is a titration? The act of adding standard solution in small quantities to the test solution till the reaction is complete is termed titration.

Potentiometric titrations involve the measurement of the potential difference between two electrodes of a suitable cell; conductometric titrations, the electrical conductance or resistance of the solution being titrated; and amperometric titrations, the electric current passing during the course of the titration.File Size: 1MB

of excess base present. The equivalence point for the titration of a strong acid with a strong base occurs when [OH–] exactly equals [H 3 O ] in the solution; pH 7.0. The situation in the case of the titration of a weak acid with a strong base is somewhat different due to the fact that a weak acid is only partially ionized in aqueous solution.

is that the visual method cannot be automated and is therefore difficult to validate and it lacks data integrity. This paper summarizes the steps involved in converting an existing manual titration procedure to semi-automated or automated titration procedures. It discusses topics such as selecting the right electrode and titration mode.
