Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

1. Why is the KMnO4 solution filtered? KMnO4 doesn't need to be filtered prior to use. Most commercial samples of KMnO4 contain some manganese dioxide that must be removed prior to use to avoid further decomposition. KMnO4 is very stable, but the unstable ions in the commercial packaging materials must be removed prior to use. Most commercial samples contain inorganic matter that will react slowly with the KMnO4 and cause its decomposition. 2. Why is the KMnO4 not stored in a rubber-stoppered bottle? Rubber doesn't make a good seal with the plastic bottles in which permanganate is usually stored. Rubber is made of inorganic matter and will reduce the permanganate solution. Rubber is made of organic matter and will reduce the permanganate solution. Rubber can oxidize the permanganate solution.
