This natural indicator is easy to extract as well as easily available. Indicators used in titration show well marked<\/p><p>changes of colour in certain intervals of pH. Most of these indicators are organic dyes and are of synthetic origin. Today synthetic<\/p><p>indicators are the choice of acid-base titrations. But due to environmental pollution, availability and cost, the search for natural<\/p><p>compounds as an acid-base indicator was started. Herbal indicators are evaluated by using strong acid-strong base, strong acid<\/p><p>weak base, weak acid-strong base and weak acid weak base. In all these titrations the methanolic extract of the flowers of <i>Tagetes <\/i><\/p><p><i>erecta <\/i>was found to be very useful, economical, simple and accurate for acid base titration.<\/p><\/div><div><h3>How to Cite this paper?<\/h3><div><p><span style=\"font-weight: bolder\">APA-7 Style<\/span><br \/><span style=\"font-family: Arial, Helvetica, sans-serif;font-size: 15px\">A.
