explain the terms oxidation and reduction with help of an example
Answers
Oxidation is the loss of electrons. In terms of oxygen transfer, oxidation may be defined as the chemical process in which a substance gains oxygen or loses electrons and hydrogen. When one of the reactants is oxygen, then oxidation is the gain of oxygen. Reduction is a loss of oxygen.
ex-
The iron metal is oxidized to form the iron oxide known as rust. Electrochemical reactions are great examples of oxidation reactions. The copper metal is oxidized. Silver metal whiskers grow onto the copper wire, while copper ions are released into the solution.
Reduction is a chemical reaction that involves the gaining of electrons by one of the atoms involved in the reaction between two chemicals. The term refers to the element that accepts electrons, as the oxidation state of the element that gains electrons is lowered.
ex-
Reduction can be considered as the removal of oxygen, the addition of hydrogen, or the gain of electrons. Removal of oxygen: Metal ores which are oxides are reduced to the metal - this is how iron is made from iron ore. The reducing agent is carbon monoxide
