Question 2.

Write answers to the following.

What is the reaction called when oxidation and reduction take place simultaneously? Explain with one example.


Answer:

When oxidation and reduction takes place simultaneously, the reaction is called redox reaction.


Oxidation: losing of electrons Reduction: gaining of electrons


Redox Reaction = Reduction + oxidation


For example:


CuO + H2→ Cu + H2O


i. In the reaction, CuO loses oxygen atom which means that reduction of CuO(copper oxide) takes place.


ii. H2 (hydrogen) takes up oxygen atom.


iii. As a result, formation of water takes place. This means hydrogen undergoes oxidation.


iv. Oxidation and reduction are taking place at the same time, thus it a redox reaction.
