The Potential of Clitoria ternatea L. Extracts as an Alternative Indicator in Acid-Base Titration

Experiments are an important part of the chemistry curriculum. An indicator in form a synthesis is commonly used acid-base materials experiments. The usage synthetic indicators can result waste that both environmentally harmful and costly. butterfly pea flower one plants contains anthocyanins, which have potential to be as alternative indication natural acids bases. study aims determine acid base material curriculum competency indicators, well extract substitute for practicality chemical experimental design SMA/MA. This employs descriptive qualitative research method includes literature review, observation, experimentation, interviewing. results showed relationship between experiments was determination pH solution, identification properties, titration. produced from maceration extraction using 96% ethanol solvent. gives pink color at 1-2, reddish purple 3, light 4-5, turquoise 6, bluish green 7, blue 8-9, 10, yellowish 11, greenish yellow 12-13, 14. titration step could replace namely phenolphthalein methyl orange. Based on analysis, schools.
