Classifications of Acids
Acid can be classified into various categories
On the Basis of Origin
On the basis of origin, acid can be classified into two categories which are discussed below,
- Organic Acids: The acids that come from organic matter like plants and animals are known as Organic Acids. For Example, citric acid (Citrus fruits), Acetic acid (Vinegar), Oleic acid (Olive oil), etc.
- Mineral Acids: The acids that come/are produced from minerals are known as Mineral Acis or Inorganic Acids. These acids do not contain carbon For Example H2SO4, and HCl. HNO3, etc.
On the Basis of Strength
On the basis of strength, acid can be classified into two categories which are discussed below,
Strong Acids: A strong acid is one that can be totally or nearly completely dissociated in water. For Example, Sulphuric acid, Nitric acid, Hydrochloric acid, etc.
H+ + H2O ⇢ H3O+
HCl(aq) ⇢ H+(aq) + SO4–(aq)
H2SO4(aq) ⇢ 2H+(aq) + SO4–(aq)
Weak Acids: A weak acid is one that does not completely dissociate or dissociates very little in water. For Example, the acids that we consume on daily basis like citric acid, acetic acid, etc.
CH3COOH(aq) ⇢ CH3COO-(aq) + H+(aq)
HCOOH(aq) ⇢ HCOO-(aq) + H+(aq)

Acids and Bases
An acid is a substance that is capable of donating a proton (hydrogen ion) to another substance. A base is a molecule able to donate OH- ion/strong>. Acidic substances are usually identified by their sour taste.
Acids have a sour taste and are corrosive i.e. exposure to acid on human skin can cause blisters. Some examples of acids are HCl, H2SO4, and others.
Let’s learn more about acids and bases, their properties, theories, and others in this article.
