Potassium permanganate is available as a dry, purplish solid. A device injects a solution of potassium permanganate into the water between the water pump and holding tank. Potassium permanganate oxidizes iron, manganese, and hydrogen sulfide into particles. The water should be colorless when it leaves the filter.

It has a solubility in water of 5.0 g/100 ml at 20°C and is available at a commercial strength of 97-99% potassium permanganate. Use: Weigh out 2.5 g of potassium permanganate. In a 150-ml acid-washed beaker, dissolve the sample with 100 ml of deionized distilled water.

Potassium Permanganate Solution is a mild antiseptic and drying agent which can be used on weeping and infected areas of the skin. It can be used as a soak for treating small areas such as hands and feet or added to your bath to treat your whole body.

1. Bath. Fill a tubful with the solution and use for bathing.
2. Compress. Moisten strips of cotton or gauze in the solution.
3. Soak. Fill a bathtub or a basin with enough solution to immerse the affected areas.
4. Wash. Dip cotton or a gauze in the solution and use to wash affected areas.

If bromine water is put into a glass of cycloHEXANE, the solution will turn the yellowish/orange colour of the bromine water, as no reaction takes place, whereas if it is put in cycloHEXENE, the solution will go colourless, as the bromine bonds with the cyclohexene.

Cyclohexane

Pentane

Octane

Pentane is a nonpolar molecule, hence, it will only dissolve in nonpolar solvents like cyclohexane.
