“Clitoria Ternatia-A natural indicator of use”,

Author: GOUR DASMOHAPATRA, NARAYAN CHANDRA BISWAS
Abstract: Synthetic indicators due to chemical hazards causing environmental pollution, availability and cost, the search for natural compounds as an acid-base indicator was started. A study therefore has been carried out on clitoriaternatea for its use as natural acid-base indicator. The flower contains anthocyanine pigment, whose colour changes depends on the solution pH.The acid-base equilibrium of this pigment was investigated using spectrophotometric method. The pKind values were found to be 2.8 and 7.04 . The experimental results using this natural flower indicator is compared with other flower indicator such as hibiscus subdariffa as well as with synthetic indicators such as phenolphthalein and methyl orange. The titration values were also compared with the results obtained on the basis of conductometric and pHmetric titrations. The titration results reveals superiority of clitoriaternatia over other indicators used in the present investigation.
Keyword: Clitoriaternatia; flower indicator; acid-base neutralization; pK values; pH metric – conductometric titration.
