it is mainly used to find out the errors, hence serve as a useful tool in precise measurements and accurate results.
to reduce error
Performing a "blank" titration is used as a reference for your real titrations. You obtain consistent results if you use the same endpoint color from your reference.
used to determine the concention in solutions
Types of titrations 1. Direct titration: analyte + titrant → product 2. Blank titration: titration of a solution not containing the analyte (check for errors) If the endpoint is unclear, we can use a . . . Back titration a. Excess of standard solution is added to analyte (and they react) - Step 1 b. A second standard titrates the excess (unreacted) standard - Step 2 Step 1: analyte + reagent 1 → product + excess reagent 1 Step 2: excess reagent 1 + reagent 2 → product
types of conductometric titration: acid base titration complexometric titration replacement titration redox titration precipitation titration

over titration is when too much titrant is added to the analyte in a titration procedure.
Titration is a method of chemical analysis; for example: - volumetry - potentiometric titration - amperometric titration - radiometric titration - Karl Fisher titration - spectrophotometric titaration - viscosimetric titration and other methods
During an experiment for chemistry, if an indicator will not work due to the lack of a reactant, the reactant can be added. You must then compensate for the added amount by creating a solution of the indicator and the the same amount of the reactant. The volume required in the blank titration must then be subtracted from the other results to obtain quality results. This is an indicator blank and how it is used.
There are various types of titration. It is dependent on the conditions used and the reactants and desired products. Some of them are acid-base titration, redox titration, colorimetric titration and thermometric titration.
