Question

Soap micelles in water will not come together to precipitate because of: (A) Ion-ion attraction between micelles (B) Ion-ion repulsion between micelles (C) Electro negativity of micelles (D) Electro positivity of micelles

Answer 1

Hello Student,

◆ Answer -

(B) Ion-ion repulsion between micelles

● Explanation -

• Micelle is aggregate of soap molecules in the solution.
• When soaps dissolve in water, hydrophobic end of soap molecules concentrate around the dirt and form micelles.
• As similar ions are present near each other, they repel each other and don't precipitate.
• Instead they form a colloidal solution.
