The permanganate ion (MnO−4) ( MnO 4 −) is a deep purple color, and upon reduction converts to a brown precipitate (MnO2) ( MnO 2).Solubility. Solubility describes how much of a solute can dissolve in a given volume of a specific solvent. Solubility is usually reported in terms of solute mass per solvent volume or solute mass per solvent mass. For example, the solubility of sodium chloride in water at room temperature is reported as 36 g per 100 mL of water.1. To the sample, add approximately 50 mL of laboratory water and stir continuously with a glass stirring rod for about two minutes.
