ABSTRACT:
For detection of end point in acid-base titrations used indicators are synthetic. Indicators assist to find out the equivalence point in acid- base titrations. Indicators show quick color change with respect to change in pH. Hamelia patens Jacq belonging to family- Rubiaceae. A study has been done to examine the indicator action of methanolic extract of flower and compared with that of previously present synthetic indicators. The present study reported the use of Hamelia patens Jacq flower extract as an acid base indicator in different types of acid base titrations. Flowers were extracted using methanol, a specific volume was added which gave perfect and reliable results for all the four different types of neutralization titrations - strong acid against strong base, strong acid against a weak base, weak acid against strong base and weak acid against weak base. The work shows that natural indicator was very useful, economical, simple and accurate.
