Titratua

Titratua is the Basque-language term used for titration, a quantitative chemical method used to determine the concentration of a solute in a solution. In a titration, a solution of known concentration (the titrant) is added gradually to a measured volume of another solution (the analyte) until a defined chemical reaction reaches its endpoint. The endpoint is identified by a visible indicator, a pH meter, or other instrumental measurements. From the known titrant concentration and volume, and the measured analyte volume at the endpoint, the analyte’s concentration can be calculated using stoichiometric relationships.

Common titration types include acid–base titration, redox titration, complexometric titration, and precipitation titration. Standard laboratory practice uses equipment such as a burette for delivering the titrant, a pipette for measuring the analyte, and a flask for the reaction. Visual indicators like phenolphthalein or methyl orange are often employed, while modern methods frequently rely on pH or conductometric data to determine the endpoint more precisely.

Titratua has wide applications across chemistry and related sciences. It is used in pharmaceutical analysis to determine active ingredient concentrations, in environmental testing to assess water quality, in food and beverage control, and in clinical laboratories for various assays. Accuracy depends on proper standardization of the titrant, careful measurement of volumes, and correct interpretation of the endpoint. In Basque-language education and scientific literature, titratua denotes both the procedural act and the resulting quantitative outcome of the titration.
