Titration is a laboratory technique used to determine the concentration of a solution. It involves adding a solution of known concentration, called the titrant, to a solution of unknown concentration until a chemical reaction reaches its endpoint. This endpoint is often indicated by a color change, which helps identify when the reaction is complete. The process typically uses a burette to deliver the titrant precisely. Common applications of titration include analyzing the acidity of solutions, determining the concentration of various substances, and quality control in industries such as pharmaceuticals and food production.
