Flower Extract as An Organic Indicator in Acid Base Titration

Abstract

Indicators are very essential chemicals. Therefore, for all types of acid base titration, synthetic indicators have always been the preferred option. As they show a sharp color change at intervals of pH in all types of titrations. However, due to certain disadvantages like high cost, availability problems, long process and complex synthesis, hazardous waste product and environmental issues, an attempt is required to substitute synthetic indicator with natural indicator. From maceration of flowers, anthocyanin color pigment was produced. A UV-Visible spectrophotometer was used to measure the quantitative amount of color pigment.
