Interaction between Colloids-Gold Number
Interaction between Colloids-Gold Number - It is known that lyophobic sols are unstable. They are however stabilized by adding stabilizers. When two lyophobic sols are mixed together, they may coagulate by mutual neutralization of electric charges or by destroying each others st..
Gold Number
It is the number of milligrams of the protective colloid which just prevent coagulation of 10ml of standard gold sol when 1 ml of 10% solution of sodium chloride is added to it. Different lyophilic sols have different gold numbers. Smaller the gold number of..
