A microscale method was developed for the determination of titratable acidity of tea (Camellia sinensis) and compared with the recommended method. The results obtained show that the method developed is satisfactory: the values obtained are very similar to those of the reference method and showed a linear correlation with a value of R2 = 0.8901. The method developed can be used as a teaching method in chemistry laboratories for the physicochemical characterization of drinks made from Camellia sinensis.
