define oxidation and reduction with example.
Answers
Answer:
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. ... The opposite process is called reduction, which occurs when there is a gain of electrons or the oxidation state of an atom, molecule, or ion decreases.
Explanation:
Reduction is the loss of oxygen atom from a molecule or the gaining of one or more electrons. A reduction reaction is seen from the point of view of the molecule being reduced, as when one molecule gets reduced another gets oxidised. The full reaction is known as a Redox reaction
Answer:
Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction.
Example - when iron combines with oxygen to form iron oxide or rust. The iron is said to have oxidized into rust. The chemical reaction is: 2 Fe + O2 → Fe2O3. The iron metal is oxidized to form the iron oxide known as rust.
Reduction involves a half-reaction in which a chemical species decreases its oxidation number, usually by gaining electrons. The other half of the reaction involves oxidation, in which electrons are lost. Together, reduction and oxidation form redox reactions (reduction-oxidation = redox). Reduction may be considered the opposite process of oxidation.
Example - An example of a reduction is when iron reacts with oxygen, forming iron oxides (commonly known as rust). In that example, the iron is oxidized and the oxygen is reduced.
