chemical properties uses of oxygen

Oxygen (dioxygen) is neutral and has no action towards blue or red litmus. It is a supporter of combustion. Oxygen is quite a stable compound due to high bond (dissociation) energy of O = O bond. Its bond energy is 495 kJ mol - 1 . So,..

Neutral character Oxygen is neither acidic nor basic. Both blue and red litmus are unaffected by oxygen..

With sodium Introduce a small piece of sodium metal into a jar of oxygen. It combines with oxygen to form sodium peroxide. Allow a piece of sodium to burn in a deflagrating spoon, and then introduce it into another jar of oxygen. It burns with a brilliant ..

Ethers are relatively inert compounds inspite of the presence of oxygen atom carrying two lone pairs of electrons in their molecules. These are not easily attacked by alkalis, dilute mineral acids, metallic sodium, PCl 5 etc. under ordinary conditions. It is because of this reason that th..

Chemical Properties of Sulphur - With Air or Oxygen - When heated in air or oxygen, sulphur first melts and then burns with a blue flame to form sulphur dioxide and some traces of sulphur trioxid..

With hydrogen Hydrogen burns in oxygen to form water vapor. ..

>. Moreover, since ionization energies of O 2 and xenon are comparable he thought that an analogous reaction should be possible with xenon. He tried the reaction between Xe and PtF 6 by direct interaction and synthesized the first compound of noble gases Xe + [PtF 6 ] - in the f..

On hydration, quick lime forms slaked lime or lime water. When water is added to lime it becomes hot and cracks to form a white powder. This is called slaking of lime. Calcium oxide is a basic oxide. It can react with acids to give calcium salts. With acidic oxides like silicon dioxide an..

Calcium carbonate is precipitated when carbon dioxide is passed through a clear solution of calcium hydroxide in water. The lime water turns milky serving as a test for carbon dioxide liberation. On passing excess of CO 2 gas the milky ness disappears due to the formation of calcium..
