Why gold sol behaves like lyophillic colloid when gelatinis added to it?
Asked by mohitgehlot | 3rd Mar, 2011, 03:43: PM
When a lyophilic sol is added to any lyophobic sol, it becomes less sensitive towards electrolytes. Thus, lyophilic colloids can prevent the coagulation of any lyophobic sol.
The phenomenon of preventing the coagulation of a lyophobic sol due to the addition of some lyophilic colloid is called sol protection or protection of colloids.
Geletin is also a hydrophilic subastance, so the added gelatin acts as a protector to the gold sol.
We hope that clarifies your query.
