End Point

What is End Point?

The end point (or endpoint) of a titration is the point at which the indicator changes colour, signalling that the reaction between the titrant and the analyte is approximately complete. The end point is ideally very close to the equivalence point (the stoichiometric completion of the reaction), though they are not always identical. Careful choice of indicator minimises the end-point error.
