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
