An acid-base titration is an experimental laboratory method used to determine the unknown concentration of an acid or a base solution. This quantitative chemical analysis relies on a neutralization reaction where a solution of precisely known concentration (the titrant) is added to the solution of unknown concentration (the analyte) until the chemical reaction is complete. Key Terms to Know

Titrant: The standard solution with a known molarity placed inside the burette.

Analyte: The target solution with an unknown concentration sitting in the flask below.

Equivalence Point: The theoretical point where the moles of acid exactly equal the moles of base in stoichiometric proportions.

End Point: The physical point during the experiment where the indicator permanently changes color, signaling that the titration should stop.

Indicator: A chemical substance added to the analyte that alters its color at a specific pH range to visualize the end point. The Standard Laboratory Setup

The physical procedure requires high-precision glassware to deliver accurate volume readings: Acid-Base Titration – BYJU’S
