Question

how to find out Oxygen and reducing agent of an chemical reaction with example

Answer 1

Of oxidation number incrases then substance is oxidised and is called as reducing agent

.like beforr oxidation number of O was 0 then it becomes +2 then it is oxidised and is reducing agent in the reaction

Similarly if oxidation number is reduced then substance is reduced and is called as oxidising agent

Like

H2 first has +1 oxidation state and after it becomes 0 then it is reduced and would be called oxidising agent there

Hope it helps

Thanks

Answer 2

Get an equation for finding the the oxidizing or reducing agent. For example. If in H20

As the oxidation no. oxygen is -2 equation becomes , X +(-2)= 0 . Here X is the oxidation number element that you want to find out and 0 is the neutral charge on complete molecule.
