What is titration definition?

Titration is a laboratory technique employed to determine the concentration of a substance in a solution. It involves adding a known amount of a reagent (a solution of known concentration) to the sample solution until the reaction between the two is complete. The point at which the reaction is complete is called the endpoint and is typically detected using an indicator solution (which changes color when the reaction is complete) or by measuring the pH of the solution. The amount of reagent added at the endpoint is used to calculate the concentration of the substance being analyzed in the sample solution. Titration is an important technique in analytical chemistry and is commonly used in the pharmaceutical, food, and environmental industries.
