Answer 1

Answer:

Acid, Base and Salt.

ACID: Taste of acid is sour. There are many substances that contain acid and so taste sour. For example – lemon, curd, pickles, orange juice, vinegar, etc.

Substances that taste sour are called acidic. The chemical nature of such substance is known as ACIDIC.

The word acid comes from Latin ‘ACERE’ which means sour.

BASE: Taste of base is bitter. Substances that contain base taste bitter. For example; soap or soap solution, baking soda, washing soda, etc.
