Acid-base titration

Definition

An acid-base titration is a technique used to determine the concentration of an unknown acid or base by reacting it with a known volume and concentration of another acid or base. The reaction between the two solutions allows for the determination of the equivalence point.

Indicator:

A substance that changes color when the pH of a solution reaches a certain value, helping to identify the endpoint or equivalence point in an acid-base titration.

Endpoint:

The point at which an indicator changes color during an acid-base titration, indicating that stoichiometrically equivalent amounts of acid and base have reacted.

Titration curve: A graph showing how pH changes as one solution is added to another during an acid-base titration. It helps identify important points like the equivalence point and buffer regions.
