reduction chemical reaction

The reaction in which a chemical species gains electron(s) is known as reduction..

Oxidation - Reduction Reactions - "Oxidation is a reaction in which oxygen is added or hydrogen is removed from a substance." Addition of Oxygen Oxygen adds on to magnesium to become magnesium oxide. Removal of Hydrogen Hydrogen is removed from hydroiodic aci..

Taking the example of electrolysis of molten sodium chloride, one can also learn oxidation-reduction of ions. When electric current is passed through molten sodium chloride then, sodium metal and chlorine gas are forme..

In aromatic and aliphatic nitro compounds, nitro group undergoes similar reactions. However depending on the attachment of the aryl or alkyl groups, the reactivity may be differen..

Reduction - Acyl halides are reduced to primary alcohols with LiAlH 4 and NaBH 4 . Partial reduction of acyl chloride to aldehydes can also be done by catalytic hydrogenation over palladium catalyst supported on barium sulphate. Small accounts of quinoline and sulphur are added ..

Though acetic acid is resistant to reduction, prolonged heating under pressure with concentrated hydriodic acid and red phosphorus gives ethane. This is also possible by heating the acid with hydrogen at high temperature and under pressure in the presence of a nickel catalyst. In the..

Reduction - In aromatic and aliphatic nitro compounds, nitro group undergoes similar reactions. However depending on the attachment of the aryl or alkyl groups, the reactivity may be different. Nitro compounds can be reduced to primary amines under a variety of conditions. The v..

Hydroiodic acid in the presence of red phosphoru..

Aldehydes and ketones on mild reduction give primary and secondary alcohols respectively. This type of reduction is carried out either catalytically with H 2 in the presence of Ni, Pt or Pd or chemically by LiAlH 4 (Lithium Aluminium Hydride) or NaBH 4 (Sodium boro..

When a chemical reaction occurs how are new substances produced? Do atoms of one element transform themselves into atoms of another element? Do atoms withdraw from the mixture or turn up from elsewhere? Neither of these happens; what takes place is the breaking of old bonds bet..
