The present work describes a simple hands-on experiment kit for colorimetric quantification of ferric (III) ion (Fe[superscript 3+]) in an aqueous medium using anthocyanin extracted from "Ruellia tuberosa" L. as a green indicator. The extraction of a high amount of anthocyanin was easily accomplished by using only hot water instead of an…
