1.	Explain redox reaction withsuitable example.
Answer» Solution :The reaction whichinvolvessimultaneous oxidation and reduction is called an oxidation-reduction or redox reaction. In a redox reaction, one reactant gets oxidised while the other gets reduced during a reaction. Redox reaction = Reduction + Oxidation In redox reaction, the reductant is oxidised by the oxidant and the oxidant is reduced by the reductant. Example : `CuO_((s)) + H_(2(g)) + H_(2)O` In this reaction, oxygen is removed from copper oxide THEREFORE it is a reduction of CuO, while hydrogen accepts oxygen to FORM water that means oxidation of hydrogen take place. THus oxidation and reduction reactions OCCUR simultaneously. Other examples of redox reactions : `underset("Hydrogen")(2H_(2)S) + underset("sulphide")(SO_(2)) tounderset("SULPHUR")(3S) + 2H_(2)O` `underset("Manganese dioxide")(MnO_(2))+4HCl to underset("Manganese chloride")(MNCl_(2))+2H_(2)O+Cl_(2)uparrow`
