Natural indicators with the pigments extracted from natural sources like plants, animals, minerals, etc. have been grown in the past decades due to its potential applicability over a wide range of applications and the availability of the resources. Although, these natural dyes have been used for centuries, its durability is considered as the main drawback for their applicability. However, they are eco-friendly, biodegradable, and non-carcinogenic in comparison to synthetic pigments. In this research work, the pigment was extracted from Hibiscus rosa-sinensis, i.e., shoe-flower and the extract was used as an indicator over a wide range of acid-base titrations.
