Titration is a common laboratory method that is used to determine the unknown concentration of a known reactant. Volume measurements play a key role in titration, it is also known as volumetric analysis.
A reagent, called the titrant or titrator, of a known concentration and volume is used to react with a solution of the analyte or titrand whose concentration is not known. Using a proper burette to add the titrant, it is possible to determine the exact amount that has been consumed when the endpoint is reached.
Endpoint: The endpoint is the point at which the titration is complete, as determined by an indicator. This is ideally the same volume as the equivalence point—the volume of added titrant at which the number of moles of titrant is equal to the number of moles of analyte.
In the classic strong acid-strong base titration, the endpoint of a titration is the point at which the pH of the reactant is just about equal to 7, and often when the solution takes on a persisting solid color as in the pink of phenolphthalein indicator.
Use of titration: As descrribed above, it is used to know the unknown concentration of a reactant in a solution.
Yes questions can come in competitive exams regarding this. A general idea and knowledge and formulae is necessary .
