Define Oxidation Reaction, Reduction Reaction ,Oxidizing Agent and Reducing agent. pls do explain with reaction if u can.?

Question

Answer

(i)Oxidation reaction and Oxidising agent:- Adding of
O2.
Example:- 2Cu + O2 ==> 2CuO.

In this reaction, Copper gaining the Oxygen to form Copper Oxide. This is possible when Cu and O2 is heated.

(ii) Reduction reaction and Reducing agent:- Losing of
O2 and gaining of H2.
Example:- CuO + H2 ==> Cu + H2O.

In this reaction, Copper Oxide is getting reduced to loose the oxygen and Hydrogen is getting oxygen to form water as per the chemical equation.

Answer

OXIDATION mean adding of oxygen or removal of hydrogen and in this process a substance loses electron
eg: 2Cu + O2 gives 2CuO.
in this reaction Cu is oxidized
REDUCTION mean removal of oxygen and adding of hydrogen and in this process a substance gain electron
eg: Na + H2 gives 2NaH
OXIDIZING AGENT in a reaction either supplies oxygen or removes hydrogen
eg:MnO2 + 4HCl gives MnCl2 + Cl2 + 2H2O
in this reaction MnO2 is oxidizing agent
REDUCTION AGENT in a reaction either it supplies hydrogen or removes oxygen
eg : SO2 + Br2 + 2H2O gives H2SO4 + 2Br
in this reaction H2SO4 is a reduction agent

Answer

Oxidation jab equation ke left se oxygen add ho aur right mei oxygen akele ho aur reduction jab oxygen ki jagah hydrogen ho

Answer

Oxidation Reaction
Oxidation is a chemical reaction that involves the loss of electrons from a substance. This process often results in an increase in oxidation state. When a substance is oxidized, it may combine with oxygen or lose hydrogen.
- Example:
- $ \text{2Mg} + \text{O}_2 \rightarrow \text{2MgO} $
- In this reaction, magnesium (Mg) is oxidized as it loses electrons to form magnesium oxide (MgO).
Reduction Reaction
Reduction is the opposite of oxidation; it involves the gain of electrons by a substance. This process often leads to a decrease in oxidation state. When a substance is reduced, it may lose oxygen or gain hydrogen.
- Example:
- $ \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} $
- Here, copper ions (Cu²⁺) are reduced to elemental copper (Cu) by gaining electrons.
Oxidizing Agent
An oxidizing agent is a substance that facilitates oxidation by accepting electrons from another substance. It itself gets reduced in the process.
- Example:
- In the reaction $ \text{Cu}^{2+} + 2e^- \rightarrow \text{Cu} $, the copper ion (Cu²⁺) acts as the oxidizing agent.
Reducing Agent
A reducing agent is a substance that donates electrons to another substance, causing its reduction while getting oxidized itself.
- Example:
- In the reaction $ \text{2Mg} + \text{O}_2 \rightarrow \text{2MgO} $, magnesium (Mg) is the reducing agent as it donates electrons to oxygen.
Understanding these concepts is crucial for grasping redox reactions, which are fundamental in chemistry, biology, and industrial processes.
