- Comparative Account of General Properties of Colloids explains optical, electrical, and mechanical behaviors.
- Comparative Account of General Properties of Colloids highlights differences between lyophilic and lyophobic sols.
| Property | Lyophilic Colloids | Lyophobic Colloids | Association Colloids (Micelles) |
| Affinity for Medium | Strong | Very weak or none | Amphiphilic (both water-loving and -hating parts) |
| Ease of Formation | Easily formed by direct mixing | Requires special techniques | Forms at high concentrations (above CMC) |
| Reversibility | Reversible | Irreversible | Reversible above and below CMC |
| Stability | Highly stable | Unstable without stabilizers | Moderately stable |
| Viscosity | Higher than dispersion medium | Similar to that of medium | Variable |
| Coagulation | Resistant to coagulation | Easily coagulated by electrolytes | Moderate resistance |
| Tyndall Effect | Weak | Strong | Present when micelles are formed |
| Brownian Movement | Moderate | Strong | Moderate |
| Protective Action | Acts as protective colloids | Needs protection | No protective action |
| Examples | Gum, gelatin, starch | Gold sol, sulfur sol | Soap, detergent solutions |
