Answer: Solvent-loving and generally stable.
- A Solvent-hating and unstable
- B Solvent-loving and generally stable
- C Always negatively charged
- D Unable to form a sol again once precipitated
Correct answer: B. Solvent-loving and generally stable
Explanation: Lyophilic colloids have strong affinity for the dispersion medium, making them stable and reversible, unlike lyophobic colloids.
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.
