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»

tudent,◆ 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.Hope I am useful...
