Potassium permanganate may stain the skin, nails and light clothing a brown colour. To remove fresh stains from the skin, rub over with a damp tablet of vitamin C.

Potassium permanganate is reduced by sodium oxalate. The reaction of potassium permanganate with sodium oxalate proceeds via a classic oxidation-reduction reaction. Two half-reactions make up the full reaction. In each half-reaction, chemicals either lose or gain electrons.

oxidation–reduction reaction

Na2C2O4 + H2SO4 = Na2SO4 + H2 + CO2 – Chemical Equation Balancer.

Acidic solutions of permanganate are reduced to the faintly pink manganese(II) ion (Mn2+) and water. KMnO4 spontaneously reduces in an alkaline solution to green K2MnO4, wherein manganese is in the +6 oxidation state. A curious reaction occurs upon addition of concentrated sulfuric acid to potassium permanganate.

Sugar White sugar is also readily available and can be used to neutralize permanganate solution. The reaction of permanganate and sugar is relatively slow, taking about 30 minutes for a complete reaction.

When KMnO4 is reduced with oxalic acid in acidic solution , the oxidation number of Mn changes from +7 to +2.

Potassium Permanganate (KMnO4) When it is added to water containing taste–odor compounds, the reaction is: 2 KMnO 4 + H 2 O + taste – and – odor compound → 2 MnO 2 ↓ + 2 KOH + 3 O − 2 + taste – and – odor compounds .

KMnO4 dissolves in water because the energy released when bonds form between the K+ ion and the negative end of the neighboring water molecules and between the MnO4- ion and the positive end of the solvent molecules compensates for the energy it takes to separate the K+ and MnO4- ions.

Potassium permanganate is a deep purple ionic solid which has many uses as an oxidizing agent. It is readily soluble in water.

Potassium permanganate appears as a purplish colored crystalline solid. Noncombustible but accelerates the burning of combustible material.

KMnO4 is neither acid or base. But Potassium permanganate is a salt of permanganic acid. It is a salt of a strong base and a strong acid .

Potassium Permanganate Solution Preparation

1. Dissolve 3.2 g of potassium permanganate in 1000 ml of water.
2. Heat on a water-bath for 1 hour.
3. Allow to stand for 2 days and filter through glass wool.
4. Standardize the solution in the following manner.

Potassium Permanganate structure – KMnO4 Potassium permanganate is an ionic compound consisting of a potassium cation (K+) and permanganate anion (MnO4-).

Why is KMnO4 coloured? KMnO4 has a deep purple colour. The metal ions in KMnO4 contains d electron and, therefore, charge transfer occurs from O– to Mn+. Therefore, a transfer of charge from O2- to Mn+ ion may occur in the lower energy region (visible region).

KMnO4 solutions are dark purple. When used as a titrant, as soon as the endpoint is reached and the KMnO4- is in excess, the solution has a permanent pink hue (provided that the solution is initially colorless). Thus KMnO4 acts as its own indicator.

This compound, KMnO4, is an inorganic compound used in the treatment of drinking water. It successfully eliminates sulfur and manganese odors, which give well water its unpleasant smell. This compound also disinfects the water, preventing people from drinking harmful bacteria.

* Breathing Potassium Permanganate can irritate the lungs causing coughing and/or shortness of breath. Higher exposures can cause a build-up of fluid in the lungs (pulmonary edema), a medical emergency, with severe shortness of breath. * Potassium Permanganate may affect the liver and kidneys.

Ingestion of potassium permanganate may result in damage to the upper gastrointestinal tract. Also it may cause systemic toxic effects such as adult respiratory distress syndrome, coagulopathy, hepatic-renal failure, pancreatitis and even death in severe cases.

Kusuri recommend NOT using Potassium Permanganate with salt. Please ensure that you read, understand and follow, all Health and Safety guidelines on the packet. Please do not eat, drink or smoke whilst handling chemicals.

In fact about 10-20gm of KMnO4 is enough to kill the person. KMnO4 is a very common substance and it can be acquired without any restriction by the public. Yet poisoning by it is uncommon but doctors are probably facing a death due to this substance; in fact fatal poisoning by KMnO4 is rare.

Acriflavine and Acriflavine derivates Great non-aggressive treatment for bacterial disease, and like potassium and chloramine, cleans up external wounds very well, and can be used with salt. One of the only recognised cures for dropsy when used in conjunction with salt.

Chloramine T can be very toxic in soft water. If your pH is below pH7 (acid) and has a general hardness below 6°dH (soft water) reduce the dose by 75%. Do not use with salt.

Acriflavine or commonly known as Flavin, is an acridine derivative of proflavin used as a topical antiseptic agent. It is a yellow or orange colour solution which stains the skin and may cause irritation, inflammation or blister upon contact [1].
