Aqueous solutions of potassium permanganate, KMnO4(aq), are easily recognized by their deep purple color. When potassium permanganate is added to an acidified solution of hydrogen peroxide, H2O2(aq), the color immediately disappears, leaving an almost colorless solution
The addition of KMnO4(aq) to a solution of oxalic acid, H2C204(aq), likewise produces a colorless solution but may take several minutes
Which of the following offers the BEST suggestion for a way to speed up the reaction between oxalic acid and potassium permanganate?
