A COMPREHENSIVE REVIEW ON PLANT EXTRACT AS AN HERBAL INDICATOR IN TRITREMETRIC ANALYSISAbstract
The synthetic indicators are used in acid-base titration for determination of endpoint. A part of its application, the synthetic indicators has several limitations such as toxic, costly, corrosive, etc. Thus, herbal indicators are the choice of today for acid-base titrations. The natural indicator is easy to extract as well as easily available. Promising results were obtained when it was compared against standard synthetic indicators. Titration shows a sharp color change at the equivalence point. The equivalence points obtained from the various part of the plant coincide with the equivalence points obtained by the standard indicators. These natural indicators are found to be very useful, economical, accurate and straightforward for the said titration. In this review, we mentioned the importance of some herbal indicators as per their finding reported by the earlier researcher.
