What is the difference between direct and indirect titration?

Direct titration is the most basic titration which is commonly used. It includes the process of reacting the analyte with moles of a particular excess reagent and thereby titrating this reagent with a second reagent. Indirect titration is also known as Back Titration.

What is direct titration?

Direct titration is a way to determine the contents of a substance quantitatively. Scientists may be aware of a reactant, but not know the reactant’s quantity. Direct titration is sometimes based on indicators that respond to the analyzed material, called the analyte.

What is indirect titration method?

A back titration, or indirect titration, is generally a two-stage analytical technique: Reactant A of unknown concentration is reacted with excess reactant B of known concentration. A direct titration is then performed to determine the amount of reactant B in excess.

Is back and indirect titration the same?

A back titration is a titration method where the concentration of an analyte is determined by reacting it with a known amount of excess reagent. The remaining excess reagent is then titrated with another, second reagent. A back titration may also be called an indirect titration.

What is different type of titration?

Such titrations, classified according to the nature of the chemical reaction occurring between the sample and titrant, include: acid-base titrations, precipitation titrations, complex-formation titrations, and oxidation-reduction (redox) titrations.

Why iodometric titration is called indirect titration?

Note that iodometry involves indirect titration of iodine liberated by reaction with the analyte, whereas iodimetry involves direct titration using iodine as the titrant. This absorption will cause the solution to change its colour from deep blue to light yellow when titrated with standardised thiosulfate solution.

What is meant by iodimetry?

Volumetric analysis involving either titration with a standardized solution of iodine, or the release by a substance under examination of iodine in soluble form, so that its concentration can be determined by titration, using starch as an indicator.
