plz explain by giving an example how oxidation and reduction proceed side by side?
Answers
Explanation:
In chemistry if a substance is oxidised it loses electrons in a reaction.
If a substance is reduced it gains electrons in a reaction.
A reaction that has both oxidation and reduction within it is called a REDOX reaction. We can write REDOX reactions as half equations - this can make it easier to see what is going on in the reaction.
For example, Zinc oxide can be reacted with Carbon to extract Zinc:
2ZnO + C --> 2Zn + CO2
In this reaction one of the substances is oxidised and one is reduced. If we write them as half equations:
Zn+ + e- --> Zn
C --> C2+ + 2e-
These equations show that Zn has GAINED an electron to have a neutral charge - there for it has been REDUCED.
Carbon has LOST 2 electrons to become C2+ - therefore it has been OXIDISED.
Answer:
Oxidation is defined as a process that involves a gain of oxygen or a loss of hydrogen. When a substance gains oxygen or loses hydrogen during a reaction, it is oxidized. This will happen only when there is another substance present that will either supply oxygen or accept Hydrogen from it. When this substance will accept hydrogen or supply oxygen, then in this process, it will get reduced (as reduction is defined as a process that involves a loss of oxygen or gain of Hydrogen).
Hence while one substance will gain oxygen or lose Hydrogen, the other must be present to lose oxygen or gain Hydrogen.
That is why it is said that that oxidation and reduction go hand in hand, or side by side i.e. they occur simultaneously.
