Potassium permanganate is widely used in chemical industry and laboratories as a strong oxidizing agentand also as a medication for dermatitisfor cleaning wounds, and general disinfection. Almost all applications of potassium permanganate exploit its oxidizing properties.

Potassium permanganate is used for a number of skin conditions. 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. Historically it was used to disinfect drinking water [9] [10] and can turn the water pink.

A major application of KMnO 4 is as a reagent for the synthesis of organic compounds. KMnO 4 is used in qualitative organic analysis to test for the presence of unsaturation. It is sometimes referred to as Baeyer's reagent after the German organic chemist Adolf von Baeyer. The reagent is an alkaline solution of potassium permanganate.

Aldehydes and formic acid and formates also give a positive test. Potassium permanganate can be used to quantitatively determine the total oxidizable organic material in an aqueous sample. The value determined is known as the permanganate value. In analytical chemistrya standardized aqueous solution of KMnO 4 is sometimes used as an oxidizing titrant for redox titrations permanganometry. As potassium permanganate is titrated, the solution becomes a light shade of magenta, which darkens as excess of the titrant is added to the solution.

In a related way, it is used as a reagent to determine the Kappa number of wood pulp. For the standardization of KMnO 4 solutions, reduction by oxalic acid is often used.

Aqueous, acidic solutions of KMnO 4 are used to collect gaseous mercury in flue gas during stationary source emissions testing. In histologypotassium permanganate was used as a bleaching agent. 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 typically included in survival kits: as a hypergolic fire starter [ citation needed ] mixed with antifreeze from a car radiator or glycerol and potassium permanganate[22] [23] [24] water sterilizer, and for creating distress signals on snow. Potassium permanganate is added to "plastic sphere dispensers" to create backfires, burnouts, and controlled burns.Hazard to Others. Super Moderator.

KMnO4 - Potassium Permanganate

Dissolving MnO2 What solvent can dissolve manganese dioxide? Petroleum distillates don't seem to dissolve this stuff at all. Manganese dioxide is not really soluble in anything at all. It will react with hydrochloric acid to form manganese chloride, chlorine and water. The hydrated salt is a light and quite pretty pink by the way!Do you offer a cleaner that could do the same job, replace HCl and remove the MnO2?

Yes, replacing HCl is possible, and in fact good practice. The mild organic acid chelating agents in the detergent will remove MnO2 more safely than hydrochloric acid Citranox concentrate is at pH 2. This is a very substantial difference in acidity, PPE requirements, disposal concerns, and of course user safety.

Additionally, as we are comparing a complex acidic detergent to a straight reagent, the Citranox cleaner will provide a more robust removal of residue.

It provides multiple avenues of cleaning mechanisms, including: acidic removal of inorganic residues, chelation, and emulsification. This robust residue removal would include more than just the MnO2, and would include organic oils, i. An example would be sulfates and silicates. To request these or another Alconox Inc.

The principal use for MnO 2 is for dry-cell batteriessuch as the alkaline battery and the zinc-carbon battery. It is used as a reagent in organic synthesisfor example, for the oxidation of allylic alcohols. Several polymorphs of MnO 2 are claimed, as well as a hydrated form. The complicated solid-state chemistry of this material is relevant to the lore of "freshly prepared" MnO 2 in organic synthesis.

Naturally occurring manganese dioxide contains impurities and a considerable amount of manganese III oxide. Production of batteries and ferrite two of the primary uses of manganese dioxide requires high purity manganese dioxide. Batteries require "electrolytic manganese dioxide" while ferrites require "chemical manganese dioxide". One method starts with natural manganese dioxide and converts it using dinitrogen tetroxide and water to a manganese II nitrate solution.

Evaporation of the water leaves the crystalline nitrate salt. In another process manganese dioxide is carbothermically reduced to manganese II oxide which is dissolved in sulfuric acid. The filtered solution is treated with ammonium carbonate to precipitate MnCO 3. The carbonate is calcined in air to give a mixture of manganese II and manganese IV oxides. To complete the process, a suspension of this material in sulfuric acid is treated with sodium chlorate. A third process involves manganese heptoxide and manganese monoxide.

The two reagents combine with a ratio to form manganese dioxide:. Lastly, the action of potassium permanganate over manganese sulfate crystals produces the desired oxide. Electrolytic manganese dioxide EMD is used in zinc—carbon batteries together with zinc chloride and ammonium chloride.

For these applications, purity is extremely important. EMD is produced in a similar fashion as electrolytic tough pitch ETP copper : The manganese dioxide is dissolved in sulfuric acid sometimes mixed with manganese sulfate and subjected to a current between two electrodes.International Hazard.

I can't search right now but there is plenty on the board I think. Nurdrage also has a procedure for purifying MnSO4 that is appropriate for purifying battery gunk. I can give more details later if no one else does. There are probably many more. This one dates from shortly after my joining the board and attempting a similar project. My goal was to start with battery gunk and finish with as many elements as possible.

The first thing to realise is that the stuff in batteries is a horrible mixture to work with and notoriously messy. My procedure is as follows: Mix contents of one D cell with water and filter. Filtrate contains ZnCl2. The zinc can be reduced via electrolysis. Digest the filter cake in concentrate HCl. This liberates copious quantities of Cl2 gas. If you are not able to deal with this then you should choose another acid. I added the HCl dripwise to the battery gunk in a flask using a separatory funnel and bubbled the evolved gas through a bucket of NaOH solution.

Filter the contents of the flask. The residue should be mostly graphite powder. The filtrate contains MnCl2. It will also have significant impurities of iron.

Add to this third an alkaline solution to form a precipitate. I used NaOH. Ammonia and Na2CO3 are also suggested and have some advantages. Refer to blogfast's comments in the link above. Filter and wash with water. Add the washed filter cake to the remaining two thirds of solution. It should mostly redissolve. However it is critical that some precipitation remains undissolved and that the solution appears cloudy.

The Fe impurities should be part of this suspended solid. Filter and retain the filtrate. Recrystallise this solution to retrieve pure MnCl2 or the sulfate. You should have lovely light pink crystals. To convert these crystals to MnO2, first dissolve in water. Then add alkali again. Filter out the precipitate formed and wash with water. Calcine the filter cake to form MnO2.
