Question

Classify acids based on their sources and basicity.

Answer 1

Acids are classified in different ways as follows: 

Based on their sources:

1. Organic acids: Acids present in plants and animals (living things) are organic acids. 

Example: HCOOH, CH₃COOH 

2. Inorganic acids: Acids prepared from rocks and minerals are inorganic acids or mineral acids. 

Example: HCl, HNO₃ , H₂SO₄ 

Based on their Basicity:

1. Monobasic Acid: Acid that contain only one replaceable hydrogen atom per molecule is called monobasic acid. It gives one hydrogen ion per molecule of the acid in solution. 

Example: HCl, HNO₃ 

2. Dibasic Acid: An acid which gives two hydrogen ions per molecule of the acid in solution. 

Example: H₃SO₄ , H₂CO₃

3. Tribasic Acid: An acid which gives three hydrogen ions per molecule of the acid in solution. 

Example: H₃PO₄
