Question
Sodium stearate is an anionic surfactant which forms micelles. Choose the correct statement for it from the following: – (A) It forms spherical micelles with group pointing towards the centre of sphere. (B) It forms non-spherical micelles with group pointing outwards on the surface. (C) It forms spherical micelles with group pointing outwards on the surface of sphere (D) It forms non-spherical micelles with group pointing towards the centre.
Answer: C) IT FORMS SPHERICAL MICELLES WITH GROUP POINTING OUTWARDS ON THE SURFACE OF SPHERE
