30. Explain redox reactions on the basis of electron transfer. Give suitable example |
|
Answer» Ans :- In the course of a chemical reaction between a metal and a nonmetal, electrons are transferred from the metal atoms to the nonmetal atoms. For example, when zinc metal is mixed with sulfur and heated, the compound zinc sulfide is produced. Two valence electrons from each zinc atom are transferred to each sulfur atom. Since the zinc is losing electrons in the reaction, it is being oxidized. The sulfur is gaining electrons and is thus being reduced. Anoxidation-reduction reactionis a reaction that involves the full or partial transfer of electrons from one reactant to another.Oxidationis the full or partial loss of electrons or the gain of oxygen. Reductionis the full or partial gain of electrons or the loss of oxygen. Aredox reactionis another term for an oxidation-reduction reaction. |
