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 MnOh..

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 melts and t..

Laboratory Preparation of Oxygen - 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..

Metals are very reactive. They form compounds with other elements easily. Sodium (Na) and potassium (K) are some of the most reactive metals. Metallic oxides make hydroxides (bases) (OH - ) and not acids when in solution. The oxides of metals are basic in nature, with the excep..
