I was testing some acid with Ehrlich reagent. Tested two different blotter edges and it showed a blue-purple color change. Out of my curiosity i put one drop in a piece of paper which was a printed white paper and guess what that also turned to blue. :d .
Am I doing something wrong or the stuff is bad? The color of the reagent was red and it 4 years old.
