Acidic substances are usually identified by their sour taste. An acid is basically a molecule which can donate an H+ ion and can remain energetically favourable after a loss of H+. Acids are known to turn blue litmus red.
Bases, on the other hand, are characterized by a bitter taste and a slippery texture. A base that can be dissolved in water is referred to as an alkali. When these substances chemically react with acids, they yield salts. Bases are known to turn red litmus blue.
Answer:
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.
Well there are many natural acids but you have requested 5 natural acids and their source so they are
1 Malic Acid- Apple.
2 Citric Acid- Lemon.
3 Formic Acid- Stings of ants and bee's.
4 Lactic acid- Curd.
5 Hydrochloric acid- Gastric juice.
Please note that Hydrochloric acid is not a natural acid but since it is found in Gastric juice so i have included Hydrochloric acid in my answer.
