We did the Iodine,Vinegar,Pr and Ph tests. Iodine was to test for starch.The vinegar was to see if it fizzed.Pr was to see if it was an acid or a base, and the Ph was the litmus paper. We compared our results with our other tests.
My group thought that the powder was green from the Iodine test. Purple from the little crystals in the powder and red from the Litmus paper.
