What happens when you add KMnO4 to an alkene?

What happens when you add KMnO4 to an alkene?

Another reaction that alkenes undergo is oxidation. When a purple solution of the oxidizing agent KMnO4 is added to an alkene, the alkene is oxidized to a diol and the KMnO4 is converted to brown MnO2.

Why is potassium permanganate used in water treatment?

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 and can turn the water pink.

Is sodium permanganate toxic to humans?

Acute inhalation toxicity data are not available. However, airborne concentrations of sodium permanganate in the form of mist may cause irritation to the respiratory tract for some. Liquid permanganate, if swallowed, may cause burns to mucous membranes of the mouth, throat, esophagus, and stomach.

What is sodium permanganate used for?

Sodium permanganate (NaMnO4) is a liquid chemical oxidant that is used to treat chlorinated solvents that contaminate soil and groundwater. It is a powerful oxidant that remediates chlorinated ethene compounds quickly and effectively.

How do you make sodium permanganate?

Sodium permanganate can be easily prepared by reacting a mixture of sodium hypochlorite and sodium hydroxide, with freshly prepared manganese dioxide. While easy to do, this reaction will only give small amounts of sodium permanganate, as during the process most of the hypochlorite decomposes.

How do you neutralize sodium 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.

How do you neutralize KMnO4?

How to neutralize: Use 3% Hydrogen Peroxide to immediately neutralize (deactivate). Dose: 2 tbsp per 100 gallons (1 cup per 500 gal). Wait 4 days after neutralizing before treating again with Potassium Permanganate Solution.

How do you reduce potassium permanganate?

Since it is a potent oxidixing agent, potassium permanganate can be easily reduced by a reducing agent. An oxalate salt is a common candidate for this. By standardizing a permanganate solution and then reacting it with an oxalate salt, it is easy to reduce potassium permanganate in a laboratory setting.
