Crystals or granules are dark purple with a metallic sheen, sometimes with a dark bronze-like appearance. Free-Flowing Grade is gray due to an additive. Potassium permanganate has a sweetish, astringent taste and is odorless.
Potassium Permagnate Also known as KMnO4, Condy%u2019s Crystals and permanganate of potash. Its frequent uses is for various field like Purifying water, Creating an antiseptic solution, As an anti-fungal treatment for the hands and feet, As a cholera disinfectant, General disinfectant agent.
Proceed with caution, however. The information provided in this article is intended for emergency situations only. Caution should be exercised when using any of the following information.
Potassium permanganate will start a fire when mixed with a couple of different compounds. Glycerin is the most common, but antifreeze will also do the trick. Antifreeze seems to create a reaction that is a little more violent. Be very careful when using either. The reaction is not always immediate. It can take several seconds for the reaction to start a fire %u2013 let it be.
After gathering all the necessary fire tinder and large pieces of wood to keep your fire going, place a teaspoon of Potassium permanganate on a flat surface. Carefully add the same amount of Glycerine or Antifreeze evenly on top of your pile. Next, stand back a couple of feet and wait at the ready with your tinder.
Mix sugar in with the Glycerin before adding to your Condy%u2019s Crystals, and you%u2019ll get a decent signal smoke.
For water purification, its use is relatively straight forward. First, if there is any sediment in the water, strain it out. Then add 3 %u2013 4 crystals per liter of water. Stir or shake for a few seconds then let sit for 2 hours. The water should be a light pink (a concentration of 1:10,000) %u2013 no darker.
Here are some proportions for killing the different nasty organisms that can find their way into water:
Bacteria requires a minimum of 2.5mg per liter of water.
Viruses require a minimum of 50mg (close to danger levels) per liter.
Potassium permanganate can become toxic in high concentrations, just like anything. The lowest recorded instance of a person poisoned was 100mg per kilogram of body weight. That said, the LD50 scale for Potassium permanganate is 1900mg per kilogram of body weight.
Just remember, as long as it is pink %u2013 it%u2019s probably ok to drink.
To use as an antiseptic, anti-fungal treatment, or emergency snow signal, add crystals one by one until the solution turns purple. Shake and use to flush out a wound, soak a fungal infection, or to leave a message in the snow.
Don%u2019t eat snow marked in yellow %u2013 just saying.
Ideally, Potassium permanganate should be stored in a nonreactive plastic bottle with a Teflon coated cap. Most plastic bottles and non-coated caps should be fine.
Potassium permanganate is not a perfect option for any of the above-listed purposes. If other more convention options are available %u2013 use them first. What it does do is offer another option should you find yourself with it as your only resource.
Its Dose Depends according to application.
TYPICAL and Common use :
Ethylene absorbents extend storage time of bananas even at high temperatures. This effect can be exploited by packing bananas in polyethylene together with potassium permanganate. By removing ethylene by oxidation, the permanganate delays the ripening, increasing the fruit's shelf life up to 4 weeks without the need for refrigeration.

Potassium permanganate is used extensively in the water treatment industry. It is used as a regeneration chemical to remove iron and hydrogen sulfide (rotten egg smell) from well water via a ‘Manganese Greensand’ Filter. ‘Pot-Perm’ is also obtainable at pool supply stores and is used additionally to treat waste water. Historically it was used to disinfect drinking water.It currently finds application in the control of nuisance organisms such as Zebra mussels in fresh water collection and treatment systems.
Almost all applications of potassium permanganate exploit its oxidizing properties. As a strong oxidant that does not generate toxic byproducts, KMnO4 has many niche uses. One of the uses can be said to be as a fixative. This list is by no means the only applications that Potassium Permanganate is used for, but it covers some of the more common applications. The optimum condition under which it is to be used can be easily established through technical service evaluations or laboratory testing.
Water Treatment – Oxidizes iron, manganese, and hydrogensulfide; controls taste and odor; and is an alternate pre-oxidant for Disinfection By-Product (THMs and HAAs) control. Variety of disease causing organisms including bacteria, yeast, fungus, spores, and viruses growing in water. Drinking Water disinfectant can also be done by other common process process is to add 1-pound of calcium hypochlorite in granular form in to 10,000 gallons of drinking water. And Calcium Hypochlorite is widely available for use as swimming pool chlorine tablets or white powder that is much more stable than chlorine. And we have H2S vial (Bacteriological ) Kit use for checking microbiological quality of water. Water borne diseases like typhoid ,cholera, diarrhoea and jaundice and caused by polluted water supply.
Municipal Wastewater Treatment – Destroys hydrogen sulfide in wastewater and sludge. Improves sludge dewatering. Industrial Wastewater Treatment – Oxidizes hydrogen sulfide, phenols, iron, manganese, and many other organic and inorganic contaminants; resultant manganese dioxide aids in removing heavy metals.
Metal Surface Treatment – Conditions mill scale and smut to facilitate subsequent removal by acid pickling in wrought metals manufacturing and jet engine cleaning. Purification of Gases – Removes trace impurities of sulfur, arsine, phosphine, silane, borane, and sulfides from carbon dioxide and other industrial gases.
Mining and Metallurgical – Aids in separation of molybdenum from copper; removes impurities from zinc and cadmium; oxidizes flotation compounds. Removes iron and manganese from acid mine drainage.
Chemical manufacture and processing: Aids in synthesis of organic products for the chemical process and pharmaceutical industries.
Aquaculture (fish farming): Controls fish diseases and parasites, and detoxifies poisons while relieving oxygen depletion in fish ponds.
Air and gas purification: Removes pollutants from air and impurities from industrial gases, and quenches slag from foundry operations.
Fumigation of Poultry farms, Hatcheries, Mushroom farms, other culture environment and Operation theatres in Hospitals.
