Abstract

An indicator of acid base is a substance which changes color as the pH of a solution changes. There are hundreds of different measures of acid base, many of which can be derived from common plants. At different pH values each indicator shows a wide set of colors. Many more chemical indicators are used in the titration of acid base, but they are slightly costly and are inaccessible so attempts are made to prepare natural indicators from plant parts. Given that these plants are very popular and easily available, the indicator obtained from them will therefore be economical. Current research work emphasizes the use of the Hylocereus undatus peel extract in different forms of acid base titrations as an indicator of acid base. The point of equivalence obtained by extract of plant species balanced with point of equivalence obtained by standard indicators.
