Question

Give two differences between oxidation and reduction reactions.

b. Identify the types of reactions:

Answer 1

Oxidation reaction::::
1.) In oxidation reaction oxygen is added or hydrogen is removed from the reactants.
.
.
OR

2.) Oxidation is a reaction in which there is increase in the oxidation number.
.
Reduction reaction:::;
1.) During this reaction hydrogen is added or oxygen is removed.
.
2.) During this reaction there is reduction in the oxidation number of the reactants.
.
Mostly all the combustion reaction is an oxidation reaction.

2Na + O2 ======>Na2O2 (oxidation reaction )

Cl2 +H2 =========>2HCl (Reduction reaction)

Answer 2

$\underline\bold{\huge{Answer !!}}$

$\underline\bold{\large{Oxidation\:Reaction}}$
In this reaction either oxygen is added or hydrogen is removed.

$\underline\bold{\large{Reduction \:Reaction}}$
In this reaction either hydrogen is added or oxygen is removed.

$\underline\bold{\large{For\:Example:-}}$

H2S + Cl2 =====》S + 2HCl

In the above reaction Hydrogen is added to chlorine , hence chlorine is reduced.
And Hydrogen is removed from Hydrogen Sulphide, hence H2S is oxidised.
