7. What do you mean by Oxidation and reduction Explain with two examples each
Answers
Oxidation is the loss of electrons during a reaction by a molecule, atom or ion. Oxidation occurs when the oxidation state of a molecule, atom or ion is increased. 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.

Redox is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
Examples of Reduction
The copper ion undergoes reduction by gaining electrons to form copper. The magnesium undergoes oxidation by losing electrons to form the 2+ cation. ... The iron oxide undergoes reduction (loses oxygen) to form iron while the carbon monoxide is oxidized (gains oxygen) to form carbon dioxide.

An example of a reaction is that between hydrogen and fluorine gas to form hydrofluoric acid:
H2 + F2 → 2 HF
In this reaction, hydrogen is being oxidized and fluorine is being reduced. The reaction may be better understood if it is written in terms of two half-reactions.
H2 → 2 H+ + 2 e-
F2 + 2 e- → 2 F-
Note:- there is no oxygen anywhere in this reaction!
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.
