Abstract
Due to increasing demand in sustainability and non-toxic alternatives in chemical practices has driven interest in naturally occurring pH indicator from plant sources. This study explores the potential of Catharanthus roseus flower aqueous extract (commonly known as Madagascar periwinkle) as a pH indicator in acid-base titrations. Aqueous extract of Catharanthus roseus has been investigated as it has the same indicator activity compared to that of the standard synthetic indicator’s phenolphthalein. To evaluate its potential four type of neutralization titration were performed and the result had been recorded. The results shows that the green pH indicator from Catharanthus roseus has the comparable performance as that of the synthetic indicators. Thus, this green Catharanthus roseus pH indicator can be an alternative to various chemical synthetic indicators, as it is Eco-friendly, easy availability, cost-effective and most importantly provides sustainability in analytical practices. This research supports the use of Catharanthus roseus as a viable alternative to synthetic indicator, aligning with green chemistry principle by promoting biodegradable, low toxicity and renewable materials in analytical chemistry.
