An acid is a substance that has more ions concentration.
Types of acid:
1. Based on the source of origin, the acid is classified as
- Organic acid
- Mineral acid
Organic acid:

Organic acids are acids that are derived from plants and animals.
Example:
Citric acid, Latic acid, Malic acid, Tannic acid
Mineral acid:

Mineral acids are acids that are derived from an inorganic substance or source.
Example:
Nitric acid, Hydrochloric acid, Sulphuric acid
2. Depending on the quantity of water present in acids, it is classified as

- Concentrated acids
- Diluted acids
Concentrated acids:

The concentration of acid is more compared to that of water. These are pure acids.
Diluted acids:

Dilute acids are acids that contain high quantity of water than concentrated acids. They're made by diluting a concentrated acid with water.
Note: In strong acids there is a complete dissociation of ions, and in weak acids there is a partial dissociation of ions in an aqueous solution.

Nitric acid, sulphuric acid and hydrochloric acids are some of the strong acids, whereas citric acids, lactic acids are weak acids.

- The acids taste sour.
- Acids are water-soluble.
- Acids turn blue litmus into red.
- Due to their corrosive nature, acids corrode metals such as aluminium and iron. As a result, these are stored in glass containers rather than metal containers.
