When Potassium chlorate is heated strongly it decomposes to give oxygen. But if a catalyst like manganese dioxide is mixed with it, oxygen is liberated at much lower temperature, in much shorter time. Potassium chlorate and manganese dioxide are mixed in the ..

A mixture of potassium chlorate (KClO 3 ) and manganese dioxide (MnO 2 ) (4 : 1) is heated in a dry test tube. The oxygen evolved is collected over water. The decomposition of KClO 3 is accelerated even at lower temperatures as MnO 2 acts as a catalyst...

During fermentation of grape juice, a brown crust is formed at the top and is called argol, which contains potassium hydrogen tartrate. It is used for the prepartation of tartaric acid and Rochelle salt (potassium sodium tartrate..

Potassium nitrate is used in the preparation of gun powder (mixture of charcoal, sulphur and potassium nitrate) and other explosives. When gun powder is ignited, it explodes. It is also used in salting and pickling of meats, to which it imparts a red col..

Chlorine is used for bleaching cotton, linen, wood pulp, etc. It is used in the sterilization of drinking water, and the water in swimming pools. The strong oxidizing action of chlorine destroys organic matter like bacteria, fungus and other micro-organisms. In most of t..

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 the compounds like lead dioxide, trilead ..

Usually air is associated with burning, and without air or oxygen, substances do not burn. But air not essentially used for all types of burning. For example, when charcoal powder is mixed with any of the substances like chlorates or nitrates of potassium or pota..

Propellants are the fuels used in rockets for propulsion. For example, alcohol, liquid hydrogen, liquid ammonia, kerosene, hydrazine and paraffin can be used as propellants. To burn them, rocket fuels require an oxidising agent. Examples are: liquid oxygen, liquid fluorine, dini..
