This work has expanded the list of natural plants (flowers) as workable substitutes to synthetic indicators in acid-base titration. The ethanolic extract of the flowers of Telfairia occendentalis and Abelmoschus esculentus showed the plants to have great potentials as indicators in acid-base titrimetric analysis because the extracts produced workable results in all the titrations conducted. Tefairia occidentalis displayed closer characteristics to phenolphthalein in weak acid – strong base and weak acid – weak base titrations and Abelmoschus esculentus with methyl orange in strong acid – strong base titration; all with values within limits. However, these plants provided workable and sustainable substitutes to the expensive, hazardous, non-eco-friendly synthetic indicators.
