STUDY OF ETHANOLIC EXTRACT OF JASMINUM SAMBAC USE AS AN ACID-BASE INDICATORAbstract
The demand for today’s chemistry is finding an efficient alternative to synthetic indicators. Acid-base titration was conducted using natural indicators in the present research work. The natural indicator is prepared from Jasminum sambac, the most commonly occurring plant. The ethanolic flower extract was used as a natural indicator. For acid-base titration, Hydrochloric acid (HCl) as strong acid and Acetic acid (CH3COOH) used as a weak acid, and Sodium hydroxide (NaOH) were chosen as a strong base. Successful results were achieved when it was examined by using standard synthetic indicators. Titration shows colour change at the point of equivalence. Thus, for acid-base titration at any dilution, natural indicators from flowers can be used. Titration with natural indicator from ethanolic flower extract of Jasminum sambac has not yet been performed by any research team. It is very simple and economical to use ethanolic flower extract of Jasminum sambac as an indicator as it provides the same outcome accuracy as that provided by the synthetic indicator.
