Answer: Stabilize the emulsion by forming a protective film around droplets.
- A Deliberately increase the size of the dispersed liquid droplets
- B Stabilize the emulsion by forming a protective film around droplets
- C Convert the heterogeneous emulsion into a fully homogeneous true solution
- D Raise the overall temperature of the emulsion to keep it liquid
Correct answer: B. Stabilize the emulsion by forming a protective film around droplets
Explanation: Emulsifying agents like soaps or proteins coat dispersed droplets, preventing them from coalescing and stabilizing the emulsion.
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.
