Question

The reaction in which oxygen is added to a substance or hydrogen is removed from a substance, is called reduction.

• A. True
• B. False

Answer 1

The correct option is B False

Oxidation involves addition of oxygen or removal of hydrogen. Reduction involves addition of hydrogen or removal of oxygen.

For example:
$\text{C(g)}+{\text{O}}_2\text{(g)}\to {\text{CO}}_2\text{(g)}$

In this reaction carbon ($\text{C}$) is getting oxidised, whereas carbon dioxide (${\text{CO}}_2$) is getting reduced.
