Preparation of Oxygen - From Potassium Permanganate - Potassium permanganate when heated, decomposes to form potassium manganate, manganese dioxide and oxygen..

Main source of oxygen are the plants which evolve oxygen as a by-product of photosynthesis. It is used chiefly by most of the living organisms in their aerobic respiration except certain anaerobics. Oxygen acts as a limiting factor in the distribution of animalsh..

It is prepared from chromite ore (FeCr 2 O 4 ). This preparation involves many step..

The common name of potassium nitrate is Bengal salt petre or nitre. It can be prepared by treating the oxide, hydroxide, carbonate or hydrogen carbonate salts of potassium with nitric acid. It is a colorless crystalline solid, soluble in water. When heated, it first m..

Any of the above mentioned methods could be used to prepare oxygen in the laboratory. Mercuric and silver oxides are not used for the preparation of oxygen, as they are very expensive. For the laboratory preparation of oxygen from any of t..

The powdered pyrolusite is fused with potassium hydroxide in presence of air to form potassium manganate, which is a green colored compound. ..
