ECO-FRIENDLY NATURAL FLOWER EXTRACT AS AN ORGANIC ACID BASE TITRATION INDICATOR

Chemicals that serve as indicators are crucial. Therefore, synthetic indicators have traditionally been the best choice for all kinds of acid-base titration. Because they exhibit a distinct color shift at pH intervals in all kinds of titrations. However, an endeavor must be made to replace synthetic indication with natural indicator due to some drawbacks, such as high cost, availability challenges, lengthy and complicated synthesis, toxic waste products, and environmental concerns. Hibiscus, Rose, and Butterfly pea anthocyanin color pigment were made by macerating flowers. The quantitative amount of color pigment was measured using a UV-visible spectrophotometer.
