Question

Soaps are ______ based soapy detergents.

  1. Water
  2. Kerosene
  3. Petrol
  4. Oil

Hint:

Soaps have a substance that soften in hot/warm water.

The correct answer is: Oil


    Soaps are Oil based soapy detergents.
    Ordinary soap is made by mixing oils and fats with alkalis. Fats and oils of animal, vegetable, and mineral origin are broken down into free fatty acids and combined with alkalis to form raw soap. This is because fats and oils dissolve or soften in hot water and easily attach to the hydrophobic ends of soap molecules. This makes rinsing easier.
