Study of Sesbania grandiflora as Natural, Economical and Effective alternative to Synthetic Indicator

摘要

Natural alternatives to synthetic chemicals are the demand of contemporary chemistry regarding environmental pollution crisis. There is need to develop green indicator as effective alternative for synthetic indicator used in laboratory. In the present, work Acid- Base titration has been performed by using natural indicators: Sesbania grandiflora (L.) pors extract. Two acids (Hydrochloric acid and Acetic acid) and two bases (Sodium Hydroxide and Ammonium Hydroxide) were selected for Acid-Base titration. 0.1N, 0.5N, 1N strength of these acids and bases were prepared. The end point obtained by flower extract coincides with the end point obtained by standard indicator. Finally it may conclude that Sesbania grandiflora flower extract as an indicator is more economical and having the same accuracy of result as that given by synthetic indicator.
