Ozone is formed in the upper atmosphere in two steps: i) Photodissociation of oxygen by ultraviolet radiations of wavelength less than 240 nm. ii) Combination of highly reactive oxygen atoms with oxygen molecules. 12. What is the principle of preparation of ozo..

Lithium aluminium hydride is one of the most popular complex hydrides. It is used as a very good reducing agent because it contains hydrogen in the form of hydride ion (H - ) and is extensively used in organic and inorganic reactions. For example, Inorganic reaction: On industrial scale it is ..

In soda water bottles, the gaseous carbon dioxide exists in equilibrium with the carbon dioxide dissolved in water. When the soda water bottle is opened, the carbon dioxide dissolved in it escapes out rapidly with fizz. This is because, the soda bottles are sealed after adding carbon dioxide gas at..

Hydrogen atom contains one proton and one electron. H + ion is formed by loss of this electron. Therefore H + ion is simply a proton. Charge density of this unshielded proton is very high. Therefore it is not likely to exist independently as H + ion. In an aqueous solution H + i..
