Abstract:
The role of indicators in acid base titration is very vast, and the synthetic indicators used for this work at a large scale. A sustainable effort has been made to replace these synthetic indicators by natural indicators. Abelmoschus Esculentus flowers appear to have very good indicating properties in acid- base titration. Indicators are used to show the end point of reaction, and this end point mainly deals with change in color, disappearance of color and precipitate formation. Three different sets of titration, viz. strong acid vs strong base, weak acid vs strong base, strong acid, and weak base, have been tested. The result of titration viz. strong acid and strong base (10mL by natural indicator and 9mL by synthetic indicator), weak acid and strong base (9mL by natural indicator and 8.7mL by synthetic indicator), strong acid and weak base (2.5mL by natural indicator and 2.8mL by synthetic indicator) showed that the natural indicators are very much effective in this regard. These values are almost similar to that obtained from synthetic indicators. Results shown above concluded that natural indicators could be an excellent replacement for synthetic indicators since they are cheap, readily available, simple to extract, not toxic, and user and environmentally friendly.
