Titröinti

Titröinti, or titration in English, is a common laboratory method used to determine the unknown concentration of a specific substance, known as the analyte, by reacting it with a solution of known concentration, called the titrant. The titrant is added to the analyte solution in small, controlled increments until the reaction is complete. This completion point is usually indicated by a visible change, such as a color change from an indicator, or measured by an instrument like a pH meter. The volume of titrant added to reach this equivalence point is then used to calculate the concentration of the analyte using stoichiometric principles. Titration is a versatile technique applicable across various scientific disciplines, including chemistry, biology, and environmental science. It is essential for quality control, chemical analysis, and research. Common types of titrations include acid-base titrations, redox titrations, and complexometric titrations, each tailored to specific chemical reactions and analytes. The accuracy of titration relies on precise measurement of volumes and a clear, unambiguous endpoint detection.
