Answer: inward, away from water.
- A inward, away from water
- B outward, toward water
- C randomly in all directions
- D into a flat bilayer sheet
Correct answer: A. inward, away from water
Explanation: The non-polar tails cluster inward to avoid water while the ionic heads face the water, forming a spherical micelle.
A typical adsorption isotherm: x/m (mass adsorbed per gram of adsorbent) rises steeply at low pressure, then flattens into a saturation plateau as the adsorbent surface fills up.
