Give examples of redox reaction

A redox reaction is a type of electrochemical reaction where oxidation and reduction occur simultaneously. Redox is the short form for “reduction and oxidation”.Example of redox reaction:i. When methane reacts with Oxygen to give Carbon dioxide and water. During this reaction Carbon is oxidised due to removal of Hydrogen and simultaneously Oxygen is reduced due to addition of Hydrogen.ii. In the reaction Copper oxide with Copper sulphate gives copper and Sulphur dioxide.During this reaction oxygen an electronegative element is removed from Copper oxide and Copper an electropositive element is removed from Copper sulphate.
