A small amount of the unknown (approximately the tip of the spatula was used for all the pigments) was added into each clean dry test tube. For the first test 1 mL of 3 M of HNO3 was added. As soon as the acid came into with the solid‚ the pigment was observed to dissolve while also turning the solution into a pale clear colour. The same amount was used for the HCl reagent. As soon as the acid touched the pigment it yielded in a clear solution (solid dissolved after a few shakes). When the KI was

RECRYSTALLIZATION Group Medical Technology Organic Chemistry Laboratory ABSTRACT Recrystallization is one of the simplest and most widely used technique for purifying organic solids through the differences in solubility at different temperatures. It is also the process in which the solid to be crystallized is dissolved to either a hot solvent or a hot solvent mixture and is cooled in a solution.In this experiment‚ acetanilide‚ the crude product of acetylation of aniline and acetic anhydride
