Procedure: Part C: First, obtain the unknown test tube that has dissolved pigment. Determine what color pigment you want to target and look use to qualitative observations from part A/B in order to find a way to determine what metal ion is likely to be inside the test tube. Since white pigment has either zinc or lead, you can target these by testing potassium iodide and record the observations, then compare them to the observations made from part A. First, obtain a 4mL test tube, and fill it with around 1mL of unknown solution, and gather 1mL of potassium iodide. Mix the two together and record the observations. Determine what white pigment metal cation is inside by comparing to part A results. Since the white pigment has been targeted, a
