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.
Properties of 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.
