Question

Soap and detergents help remove dirt from clothes. It does so because of having two parts :

1. Hydrophilic, neutrophilic
2. Both the hydrophobic
3. Hydrophilic and hydrophobic
4. Neutrophilic, hydrophobia

Answer 1

Correct Answer - Option 3 : Hydrophilic and hydrophobic

The correct answer is Hydrophilic and hydrophobic.

 

• Soap is made up of molecules with two very different ends.
• One end of soap molecules loves water - they are hydrophilic.
• The other end of soap molecules hate water - they are hydrophobic.
• The hydrophobic end does not mix with water and is therefore repelled by it.
• In water, a detergent dissolves to form detergent anions and sodium cations.
