Keywords:
Herbal indicators, Natural pH indicators, Plant-based indicators, Chemical properties of herbal indicatorsAbstract
Herbal indicators, derived from plant-based sources, offer a sustainable, cost-effective, and eco-friendly alternative to synthetic indicators in analytical chemistry. These natural compounds possess color-changing properties in response to pH variations, redox reactions, or other chemical changes, making them invaluable tools in titrations and other analytical procedures. This review explores the historical development, extraction methods, chemical properties, and applications of herbal indicators. It highlights their advantages over synthetic indicators, addresses challenges in their adoption, and identifies future research opportunities in this field.
