O KMNO4 doesn't need to be filtered prior to use. O Most commercial samples contain inorganic matter that will react slowly with the KMnO, and cause its decomposition. O KMNO is very stable, but the unstable ions in the commercial packaging materials must be removed prior to use. Most commercial samples of KMnO4 contain some manganese dioxide that must be removed prior to use to avoid further decomposition. Submit Request Answer Part B Why is the KMnO, not stored in a rubber-stoppered bottle? Rubber doesnt make a good seal with the plastic bottles in which permanganate is usually stored. Rubber can oxidize the permanganate solution. P Pearson Copyright 2020 Pearson Education Inc. All righrs reserved. Terms ofUse I Prvacy Policy Permission: 40 DELL
