Question
The protecting power of lyophilic colloidal sol is expressed in term of
Options
A.coagulation value
B.gold number
C.critical micelle concentration
D.oxidation number
Solution
Lyophilic sols are unstable, so they are stabilised by adding some lyophilic colloids which protect them from precipitation Thus, lyophilic colloids are called protecting colloids. Their protecting power is expressed in terms of gold number.
Note Lesser the gold number, Higher is the protecting power.
Note Lesser the gold number, Higher is the protecting power.
