Relation between charge and stability of colloidal gold

It is well known that the charge on colloidal gold and its stability towards electrolytes increase with the progress of dialysis up to a certain stage, after which both charge and stability begin to decrease.2 Simultaneous measurements of charge and stability towards electrolytes with the progress of dialysis have been carried out by us to see if there is any definite relationship between charge and stability of colloidal gold.The gold sol was prepared by Zsigmondy's nucleus method, with slight modifications in details
