Question

write the difference between oxidation and reduction with suitable example questions

Answer 1

$\huge\bold{ Oxidation}$

★ The addition of oxygen to a substance is called oxidation.

★ The removal of hydrogen from a substance is also called oxidation.

$\huge\bold{ Reduction}$

★ The addition of hydrogen to a substance is called reduction.

★ The removal of oxygen from a substance is also called reduction.

$\textbf{The process of reduction is just the }$
$\textbf{opposite of oxidation.}$

$\textbf{Oxidation and Reduction occur together.}$

The oxidation and reduction reactions are also called redox reactions.

$\huge\bold{Example}$

When copper oxide is heated with hydrogen then copper metal and water are formed.

$CuO + H_2\xrightarrow{\text{Heat}} Cu + H_2O$

♦ In this reaction, CuO is changing into Cu. ( oxygen is being removed from copper oxide)
So, we can say that copper oxide is being reduced to Copper.

♦ In this reaction, H2 is changing into H2O. ( oxygen is being added to hydrogen)
So, we can say that hydrogen is being oxidized to water.
