Question

How can we identify wheather the reaction is oxidation or reduction in terms of
1 - only oxygen ,
2 - Only hydrogen
Explain with example

Please give correct answer only

​

Answer 1

1. only oxygen- if the reaction and reactants combines with oxygen and there is oxygen present in product then it is oxidation reaction

2. only hydrogen- if the reaction and reactants combined with hydrogen simply there is hydrogen present then in the product hydrogen molecule also present this is how we identify oxidation and reduction.

Answer 2

Answer:

How to know if a reaction is oxidation or reduction?

We can identify redox reactions using oxidation numbers, which are assigned to atoms in molecules by assuming that all bonds to the atoms are ionic. An increase in oxidation number during a reaction corresponds to oxidation, while a decreases corresponds to reduction.

Explanation:

1. Each oxygen atom decreases its oxidation number from 0 to –2, so O2 is reduced and is the oxidizing agent

2.Each oxygen atom decreases its oxidation number from 0 to –2, so O2 is reduced and is the oxidizing agent
