Question

the process of reduction involves

Answer 1

Reduction is a process which involves; removal of oxygen, addition of hydrogen, removal of non-metal, addition of metal, decrease in +ve valency, gain of electrons and decrease in oxidation number.

Answer 2

Answer:

The process of reduction involves

• Gaining one or more electron
• Gaining hydrogen
• Losing oxygen
• Removal of non-metal
• Addition of metal
• Decrease in oxidation number

Explanation:

chemical reactions during which the number of electrons associated with one atom or group of atoms is increased or removal of oxygen or hydrogen addition is known as reduction.

For an example

$Fe_{2}O_{3} +3 CO$  →  $2Fe + 3 CO_{2}$

Here removal of oxygen and decrease in oxidation number takes place. Ferric oxide is reduced to a metal(Fe) and the reducing agent in this reaction is CO.
