Chemical structure:

Potassium permanganate is the chemical compound KMnO4. In this salt, manganese is in the +7 oxidation state. The salt is also known as "permanganate of potash" and "Condy's crystals". The permanganate ion is a strong oxidizing agent. It dissolves in water to give deep purple solutions, evaporation of which gives prismatic purple-black glistening crystals. It has a sweet taste and is odorless..

History
Potassium permanganate was discovered in 1659.

Early photographers used it as a component of flash powder
Flash Powder-->Flash powder
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Flash powder is a mixture of oxidizer and metallic fuel which burns extremely quickly and if confined will produce a loud report. It is widely used in fireworks and theatrical pyrotechnics, and was once used for flashes in photography.

Different varieties of flash powder are made from different compositions; most common are potassium perchlorate and aluminum powder. Sometimes, sulfur is included in the mixture to increase the sensitivity.

Chemically, flash powder is highly unstable. It is a heat, static, friction, and impact sensitive explosive. It is considered to be one of the most volatile pyrotechnic compositions.

Flash powders, specifically chlorate/perchlorate ones, are unique in that they produce no gas products (all solid products), which means that they are not explosives by scientific definition. (Flash powder is however regulated as a high explosive in the United States by the Bureau of Alcohol, Tobacco, Firearms and Explosives). The loud report/explosion heard from salutes and M-80s is due to the near instantaneous rise in temperature and pressure within the container, which can exceed 400 times that of standard atmospheric pressure.

Chemical applications
Potassium permanganate is used as an oxidizing agent in diverse chemical reactions in the laboratory and in industry.[1] It also serves as a disinfectant and in deodorizers. 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.

In acidic solutions, permanganate is reduced to the faintly pink [Mn(H2O)6]+2. In neutral solution, permanganate is only reduced by 3e- to give a brown precipitate of MnO2, wherein Mn is in a +4 oxidation state. KMnO4 spontaneously reduced in an alkaline solution to K2MnO4, wherein manganese is in the +6 oxidation state.

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).

Aqueous solutions of KMnO4 have been used together with T-Stoff (i.e. 80 % hydrogen peroxide) as propellant for the rocket plane Messerschmitt Me 163. In this application, it was 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.

[edit]
Biomedical uses
KMnO4 is employed to treat some parasitic diseases of fish, in treatment of drinking water, as well as an antidote in phosphorus poisoning. In Africa, it has been used to as a disinfectant for vegetables such as lettuce.


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.


A dilute (10mg/l) of potassium permanganate can be used to eliminate snails from plants prior to placing them in a fresh-water aquarium.

The intriguing story of ozone and permanganate
A curious reaction is observed when one adds concentrated sulfuric acid to potassium permanganate. Although no reaction may be apparent, the vapor over the mixture will ignite paper impregnated with alcohol. In principle (although not recommended!), this reaction could be used to produce rapid fire in a laboratory, requiring no matches or other ignition sources. Potassium permanganate and sulfuric acid react to produce some ozone, which has a high oxidising power and rapidly oxidises the alcohol, causing it to combust. An approximate equation for the ozone formation is shown below.

6 KMnO4 + 9 H2SO4 → 6 MnSO4 + 3 K2SO4 + 9 H2O + 5 O3
The H2SO4/KMnO4 reaction can also produce the oily Mn2O7, which is unstable and can decompose explosively




Cautions
Solid KMnO4 is a strong oxidizer and in general, it should be kept separated from oxidisible substances. When mixed with pure glycerine, it causes a highly exothermic chemical reaction. Thermite is sometimes ignited using this reaction. This reaction would turn red hot as a spontaneous "combustion" which would melt a glass or other container holding the reacting contents and could ignite anything flammable nearby. A comparable reaction could occur when solid KMnO4 is mixed with other organic materials. Aqueous solutions of KMnO4 are much less dangerous, especially when dilute. Solid KMnO4 with concentrated sulfuric acid forms Mn2O7, which can be explosive.[2] For example, relatively pure powdered potassium permanganate + powdered sugar will ignite (but not explode) a few seconds after a drop of water is added.

Potassium permanganate stains the hand and clothing (as it is reduced to MnO2) and should be handled with care. Clothing stains may be washed away using acetic acid. Skin stains disappear within 48 hours. In addition, mixing solid KMnO4 with concentrated hydrochloric acid generates dangerous chlorine gas. [3]

Common Usage
Potassium permanganate is often included in survival kits along with either glycerine or a glucose tablet for the purposes of making fire. The glucose tablet can be ground up, mixed with the potassium permanganate and caused to combust by applying friction. It can also be mixed with anti-freeze from a vehicle to produce flame, although this can be dangerous and should be done in a controlled manner ie dipping some paper into the anti-freeze and then adding a small amount of potassium permanganate. The ability to sterilise water and wounds is also advantageous and another reason for inclusion in a survival kit.

High-grade potassium permanganate can be found at pool supply stores and is used in rural areas to remove iron and hydrogen sulfide (rotten egg smell) from well water.

Answer 6

Both are powerful oxidants, but typically if one can use manganate you do so with preference over chromate. Chromate is dangerously toxic stuff. In the lab there is typically a Chromate waste pot. dichromate is +6 oxidation state, and this rapidly converts to chromate +5 which is one of the most powerful inorganic carcinogens. On the other hand, manganese is not that bad. Not nice, but nowhere near that bad.
