Cleaning action of soap is due to:
- A
Decrease in surface tension of water
- B
Viscosity of water
- C
High boiling point of water
- D
Polarity of water
Polarity of water: Soap molecules have polar and nonpolar regions, allowing them to interact with both water and oily substances, facilitating the removal of dirt and oils.
Therefore, the correct option for the cleaning action of soap is "Polarity of water."
Decrease in surface tension of water: Soap molecules disrupt the cohesive forces between water molecules, reducing surface tension and allowing easier wetting and removal of dirt and oils.
Viscosity of water: The viscosity of water is not directly related to the cleaning action of soap.High boiling point of water: The high boiling point of water is not directly related to the cleaning action of soap.
The cleaning action of soap is not due to high boiling point of water. It has no link with it.
Polarity of water: Soap molecules have polar and nonpolar regions, allowing them to interact with both water and oily substances, facilitating the removal of dirt and oils.
