We used titration and baseline techniques to drop the potassium permanganate into the hydrogen peroxide and sulfuric acid, and we counted how many drops it took for the solution to permanently turn purple. We recorded how long it took and how much potassium permanganate was used. We recorded our results of how long it took for the solution to turn purple and how much potassium permanganate was used. Problem: What is the baseline amount of hydrogen peroxide in a 1.5% solution?
