Redox reaction: The reaction in which both oxidation and reduction takes place, that reaction is called as redox reaction.
Oxidation: Increasing oxidation number is called as oxidation:
Reduction: Decreasing oxidation number is called as reduction.
Oxidizing agent: It self reduced and oxidise the adjacent one.
Reducing agent: It self oxidised and reduce adjacent one.
+3 -2 +2 -2 +2 -2 +4 -2
Fe2O3 + CO -----> FeO + CO2
Here Fe oxidation number decreases From +3 to +2. So Fe is reduced.
Here, C oxidation number is increased from +2 to +4. So C is oxidized. both oxidation and reduction takes place. hence it is redox reaction.
Oxidation: C
Reduction: Fe
Oxidizing agent: Fe2O3
Reducing agent: CO
0 . +1 -2 +2 -2 +1 0
Ca + 2H2O ------> Ca(OH)2 + H2
Here H oxidation number decreases From +1 to 0. So H is reduced.
Here, Ca oxidation number is increased from 0 to +2. So Ca is oxidized. both oxidation and reduction takes place. hence it is redox reaction.
Oxidation: Ca
Reduction: H
Oxidizing agent: H2O
Reducing agent: Ca
