titrante
Titrante refers to a substance that is used in a titration, a common laboratory method used to determine the concentration of a known reactant. In a titration, a solution of precisely known concentration, called the titrant, is gradually added to a solution of unknown concentration, called the analyte. The titrant is typically delivered from a burette, allowing for precise measurement of the volume added. The goal is to reach the equivalence point, where the amount of titrant added is stoichiometrically equal to the amount of analyte present. This point is usually detected using an indicator, which undergoes a distinct color change at or near the equivalence point. Alternatively, specialized sensors can be used to monitor changes in properties like pH or conductivity, signaling the endpoint of the titration. The volume of titrant used, combined with its known concentration, allows for the calculation of the analyte's concentration. Titrations are fundamental techniques in analytical chemistry and are widely used in various fields, including pharmaceuticals, environmental monitoring, and food analysis. The careful selection and preparation of the titrant are crucial for obtaining accurate and reliable results in any titration experiment.
