What happens when potassium permanganate reacts with glycerin?

As the glycerin comes in contact with the potassium permanganate, the oxidizing properties of the permanganate ion come into play with the glycerin. The oxidation of the glycerin is very exothermic and after a few seconds the released heat causes the glycerin to also ignite and burst into flame and release smoke.

How is potassium permanganate used to make oxygen?


  1. Simply add a spoonful of Permanganate crystal to the beaker.
  2. Add 20mL of 50% Hydrogen peroxide to it.
  3. Cloud of steam and oxygen splash into air!

What is the formula of glycerine?

C3H8O3Glycerol / Formula
C3H8O3 is the Molecular Formula of Glycerine In chemistry a molecular formula indicates every single atom and its numbers in a chemical compound. Hence the molecular formula C3H8O3 simply says that there are three carbon (C) atoms, eight hydrogen (H) atoms and three oxygen (O) atoms in this compound.

What is the role of glycerine in the thermite reaction?

Brief Description: Addition of a small amount of glycerine to a pile of iron (III) oxide, aluminum powder, and potassium permanganate produces a flame, sparks, and molten iron.

How do you make oxygen?

To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. As the oxygen collects in the top of the gas jar, it pushes the water out.

What is the industrial preparation of oxygen?

The most common commercial method for producing oxygen is the separation of air using either a cryogenic distillation process or a vacuum swing adsorption process. Nitrogen and argon are also produced by separating them from air.

How is potassium permanganate prepared give equation?

Preparation Of Potassium Permanganate – KMnO4 Potassium permanganate is commercially prepared by mixing solution of KOH and powdered manganese oxide, with oxidizing agents like potassium chlorate. The mixture is boiled evaporated and the residue is heated in iron pans until it has acquired a pasty consistency.

What type of solution is glycerin?

Glycerin is a simple poly compound. This solvent has a chemical formula C3H8O3. It is also known as Glycerol or glycerine. It is hygroscopic in nature.

What is the reactivity of potassium permanganate and glycerin?

Reaction of Potassium Permanganate and Glycerin is the experiment of redox reaction that consists of potassium permanganate (KMnO 4), a strong oxidizing agent, and glycerol (commercially known as glycerin or glycerine) (C 3H 5(OH) 3), an easily oxidized substance.

How to prepare KMNO₄ from potassium permanganate?

A puddle of glycerol is poured on a pile of potassium permanganate in a porcelain cup. After about 30 seconds, the reaction bursts into purple flame. Potassium permanganate is a strong oxidizer. Place KMnO₄ in dish. Add glycerol on top of potassium permanganate. Stand back. After 30 sec. the reaction mixture will burst into a purple flame.

What is the formula for potassium permanganate?

Potassium permanganate PubChem CID 516875 Structure Find Similar Structures Chemical Safety Laboratory Chemical Safety Summary (LCSS Molecular Formula KMnO4 Synonyms POTASSIUM PERMANGANATE 7722-64-7 Chamele

What type of combustion is glycerin and permanganate?

The oxidation of glycerin by potassium permanganate is an example of spontaneous combustion—combustion that occurs at or even below room temperature. The reaction proceeds relatively slowly at first; however, the rate of the reaction begins to increase as the heat produced in this exothermic reaction accumulates.
