Answer: greater coagulating power.
- A lower coagulating power
- B no coagulation at all
- C greater coagulating power
- D only reversible coagulation
Correct answer: C. greater coagulating power
Explanation: Coagulating value is the minimum concentration needed to coagulate a sol, so a smaller value means a more powerful coagulant.
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.
