In acid-base titration (i.e., the titration of an acid with a base, or vice versa), the indicator is a substance that can exist in two forms, an acid form and a basic form, which differ in colour.
Potentiometric titration can be carried out in coloured solutions while indicators cannot be used in such cases. Also, in ordinary titrations, one must have prior information about the relative strengths of acids and bases before a proper indicator is selected. However no such information is required in the case of potentiometric titrations.

Mixtures containing aspirin, acetaminophen, and salicylamide were assayed potentiometrically by nonaqueous titration. The difference in pKa values for these weak acids was sufficient to permit successful differentiation. The titrant was tetrabutylammonium hydroxide, and the titration solvent was dimethylformamide. The procedure was applied to commercial dosage forms.
general remarks. Vitamin C – or ascorbic acid – is an important antioxidant. In the cells it is easily oxidized to dehydroascorbic acid, removing oxidizing agents before they can do damage to other substances present.
The results of the analysis of two mercury(II) solutions are reported using direct potentiometry with both electrodes and by potentiometric titration using EDTA with the chloromercurate(II) electrode.
The term back titration is used when a titration is done “backwards” instead of titrating the original analyte, a volumetric solution of a reagent is added to the solution to react with the analyte, then the excess reagent is titrated.
Direct titration is the treatment of a soluble substance, contained in solution in a suitable vessel (the titrate), with an appro- priate standardized solution (the titrant), the endpoint being determined instrumentally or visually with the aid of a suitable

Potentiometric Titration of Ascorbic Acid in Vitamin C Tablets Vitamin C is another name for ascorbic acid (C 6H 😯 6, see below), a weak acid that can be determined by titration with 0.1 M NaOH. Because ascorbic acid is a fairly weak acid (pK a = 4.17), the titration will be successful only when no other acids are present in the sample. Other acids would obscure the end point of the acid-base

Potentiometric titration can be carried out in coloured solutions while indicators cannot be used in such cases. Also, in ordinary titrations, one must have prior information about the relative strengths of acids and bases before a proper indicator is selected. However no such information is required in the case of potentiometric titrations.

Potentiometric Titration. Potentiometric titration is a precipitation reaction and the compound obtained from the reaction between titrant surfactant and sample surfactant, does not have to dissociate.
The term back titration is used when a titration is done “backwards” instead of titrating the original analyte, a volumetric solution of a reagent is added to the solution to react with the analyte, then the excess reagent is titrated.
