چکیده
Dahlia pinnata is a species of the genus dahlia, belonging to the family Asteraceae. The present study reported the use of dahlia pinnata flower extract as an acid base indicator in different types of acid base titrations. The equivalence point obtained by the flower extract coincided with the equivalence point obtained by standard indicators. The results obtained by the flower extract matched with the results obtained by mixed indicator in case of strong acid and weak base, weak acid and strong base, strong acid and strong base, weak acid and weak base titration. This natural indicator was found to be a very useful, economic, simple and accurate for the said titration.
