what is potassium permanganate used for?

Answer 1

Potassium permanganate is used as an oxidizing agent in many different kinds of chemical reactions in a laboratory and in industry.[1] It is also used as a disinfectant and in deodorizers. It is used to treat some parasitic diseases of fish, and used in treatment of drinking water, as well as an antidote in phosphorus poisoning. In Africa many people have used it to soak vegetables and lettuce to neutralize any bacteria that may be present. It can be used as a reagent for the synthesis of many different kinds of chemical compounds. For example, a dilute solution of KMnO4 can convert an organic compound with a carbon-carbon double bond into a diol (glycol) compound. Stronger permanganate solutions can oxidize a methyl group on an aromatic ring to a carboxyl group. In analytical chemistry, a standardized aqueous solution of KMnO4 is sometimes used as an oxidizing titrant for redox titrations due to its deep purple color.

Deep purple-colored permanganate can be reduced to the faintly pink Mn+2 cation in an acidic solution, where Mn is in a +2 oxidation state. In an neutral solution, permanganate is only reduced to MnO2, a brown precipitate in which Mn is in a +4 oxidation state. In an alkaline solution, it is reduced to +6 oxidation state, giving K2MnO4.

KMnO4 can be used in an oxidative reaction with pseudoephedrine hydrochloride to produce methcathinone, a Schedule I drug in the United States. Consequently the DEA has restricted its use and sale by classifying it as a List I controlled precursor. Potassium permanganate is listed as a Table I precursor under the United Nations Convention Against Illicit Traffic in Narcotic Drugs and Psychotropic Substances(Red list).

Dilute solutions are used as a mouthwash (0.25%), disinfectant for the hands (about 1%) and treatment for mild pompholyx dermatitis or fungal infections of the hands or feet.

In aqueous solution was used as together with T-Stoff (i.e. 80 % hydrogen peroxide) as propellant for the rocket plane Messerschmitt Me 163. In this usage, it is known as Z-Stoff. This combination of propellants is still used in torpedoes.

It is used as a reagent to determine the Kappa number of wood pulp

Answer 4

Potassium permanganate (KMnO4) is an oxidising agent. In the estimation of available nitrogen in soil, KMnO4 is used with sodium hydroxide to evolve ammonia gas, which is collected in any dilute acid.

As it is an oxidising agent, it is used as ethylene absorbent in the container containg fruits for export. By this ripening process will be delayed.

Potassium permanganate is used in first aid during snake bite. This oxidises the snake venome in to non-toxic substance.

Potassium permanganate is used in water distillation unit to avoid salt encrustation in the boiling chamber.

Potassium permanganate solution (very very dilute concentration) is being used as crude contraceptive, as the direct contact of this chemical with uterus causes some kind of irritation, preventing the establishment of fertilised ovum.

USE PATTERNS AND FORMULATIONS

- Application sites: As a bactericidal, fungicidal, and algaecidal
agent in cooling towers, evaporative condensers, air wash systems, ornamental ponds, cooling fountains, aquaria, human drinking water, and poultry drinking water as applicable. Potassium permanganate is also used as a surface disinfectant, sanitizer, and deodorizer.

- Types of formulations: Formulations include ready-to-use liquids (0.004%-2.5%), pelleted/tableted (40%), crystals (80%-99.99%), and powder (41%).

- Types and methods of application: As a disinfectant, potassium
permanganate is diluted according to label directions and applied to hard, non-porous, inanimate surfaces. For the other uses described above, potassium permanganate is added directly to the water to be treated.

- Application rates: For cooling towers, air washers, and evaporative condensers, use 3.6 oz. of a.i./500-1,000 gal. of water, or 27-62 ppm a.i. For aquaria and ornamental ponds, use 4 ppm a.i. to control algae growth. For human drinking water treatment, use 1.1 mg of product per gal. of water (i.e., 4.4-4.5 ppm). For poultry drinking water, use 0.648 to 1.296 grains of product per quart of water (i.e., 272-543 ppm a.i.).

Answer 7

It is a very strong oxidizer which can be used as a water purifier, fire starter, fungicide and anti-bacterial agent.
