In India ways of corruption are blocked by use of vast variety of chemical based trapping methods or techniques, which involves the use of fluorescent dyes, starch powder and phenolphthalein powder, but the chemical of choice is phenolphthalein powder because it is most common, colorless, easily available and its chemistry is favorable for trapping method because it is weak acid and in unionized form it is colorless and sign of changing of colorless mode to pink indicate its ionization. Persistence of pink color during court proceedings is the major issue because, because when the court asked for proof regarding transfer of phenolphthalein and its identification, so concerning to the chemistry of phenolphthalein the pink color in ionized form is persistent for longer period if phenolphthalein is combined with hydroquinone, as well as this technique blocks the way of criminal’s plea regarding the use of laxative. So the color persistency for court trials as well as no way outs for culprit, these problems can be vanished and color of phenolphthalein can be maintained for a long period time with the help of hydroquinone.
