what is an oxidation reaction? Give an example of oxidation reaction. Is oxidation an exothermic or an endothermic reaction ?
Answers
Answer:
Oxidation reaction is a chemical reaction in which oxygen is added to or hydrogen is removed from an element, molecule or a compound.
The term oxidation was originally used to describe reactions in which an element combines with oxygen.
Example: The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium. The iron metal is oxidized to form the iron oxide known as rust. Meanwhile, oxygen is reduced.
Oxidation reactions are exothermic.
It gives net energy to its surroundings. That is, the energy needed to initiate the reaction is less than the energy released. When the medium in which the reaction is taking place gains heat, the reaction is exothermic.
Hope it helps.
