Abstract

The objective of this work is to use more plant indicators than chemical based indicators. Saraca asoca is a species of family Fabaceae and Abelmoschus esculentus and Hibiscus cannabinus is a species of family Malvaceae [1]. Indicator are very special chemicals, they change colour of the solution with change in pH by adding acid or alkali. In the present work acid base titration has been performed by using natural indicators. The natural indicator is prepared from the most commonly occurring flower Hibiscus cannabinus, Abelmoschus esculentus Saraca asoca and Hibiscus Rosa sinensis. Aqueous and methanolic extract of flower were used as natural indicator. One acid one base were selected for acid base titration. Vinegar is used as acid and caustic soda is used as base. The results obtained by the natural indicator are almost similar to the result given by the synthetic indicators. Thus, natural indicator from flowers can be used for acid base titration [2]. Using aqueous extract of flower as indicator is more economical and with the same accuracy of result as that given by synthetic indicators.
