What is the end point in titration.
In chemistry , an endpoint is the conclusion of a chemical reaction. In particular, in a titration, it is the point at which no further titrant should be added — usually indicated by a colour change in an indicator or some other measurable change.
End point is the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.
Indicator colour change is the end point of the titration. The end point is used as an approximation of the equivalence point and is employed, with the known concentration of the titrant, to calculate the amount or concentration of the analyte.
The end point demonstrates the equivalence point, typically by some form of indicator. For example, with a color indicator, the solution changes color when the titration reaches its end point.
Thanks a lot sir.
Sir, End point & Buratte reading both are different or same ?
Yes, both are same.
Thank you sir
You are welcome…
how many types of indicators use in the titrations
Mainly there are two types of Indicator used in titration.
Acid & Alkali
Phenapthaline solution is acid or alkali
Phenolphthalein solution is used as an indicator during strong acid-base titartion. This indicator is added in a strong acid solution (HCl) in the conical flask and titrated with strong alkali volumetric solution (like NaOH) filled in the burette. The end point of titration is colourless to pink colour. Phenolphthalein is colourless in acid and dark pink in alkali solutions.
