Mikalah Millheim Lab Partner: Ashlin Chavez EXP K1 February 17, 2016 II. D. Observations Run one contained everything except oxalic acid. This color began as a vibrant red and did not change. Run two contained 5 mL of oxalic acid but no sulfuric acid. This produced a color that was a bright pink at first but gradually turned into a more subtle shade of the same color. The third trial was the most interesting of this set because it saw the most change. This run had both sulfuric and oxalic acid. At first the color was as vibrant as run one but soon dulled until it went completely clear. E. The third reaction was different in that it turned to a clear color which indicated that the reaction went to completion. This also showed that the KMnO (aq) was completely consumed since it is what produced the purple/ pink hue. The presence of both H 2 SO 4 (aq) and KMnO 4 (aq) are what caused this reaction to differ than the first two. The changes seen in run two and three were relatively fast though not instantaneous.
