Endpoint and Equivalence Points in Titrations

The terms endpoint and equivalence point often get used to mean the same thing but these two terms can refer to slightly different points in a titration. The endpoint of a titration is the point at which an color change, often from an indicator added to the reaction signals that reaction is complete. Indicators are usually added to acid-base titrations to detect the equivalence point, but they are often not exact. The equivalence point is the point in the reaction where the amount (or moles) of titrant neutralizes the amount (or moles) of analyte.
