Redox reaction is a chemical reaction, that involves electron transfer between two chemical species.
* loss of an electron is oxidized
*gain of an electron is reduced.
It is also known as oxidation - reduction reaction.
Example:
Redox reaction :
H2 + F2 → 2HF
overall reaction may be written as two half - reaction.
Oxidation reaction :
Reduction reaction :
H2 → 2H+ + 2e-
* loss of an electron is oxidized
*gain of an electron is reduced.
It is also known as oxidation - reduction reaction.
Example:
Redox reaction :
H2 + F2 → 2HF
overall reaction may be written as two half - reaction.
Oxidation reaction :
H2 → 2H+ + 2e-
Reduction reaction :
F2 + 2e- → 2F-
Now we adding the reactions together the electrons are canceled.H2 → 2H+ + 2e-
F2 + 2e- → 2F-
----------------------------------------
H2 + F2
→ 2H+ + 2F-
2H+ + 2F- combine to give 2HF.
