coagultion is the process by which the dispersed phase of a colloid is made to aggregate and thereby separtate from the continuous phase. The minimum concetration of an eletrolyte in milli-moles per litre of the electrolyte solution which required to cause the caogultion of colloidal sol is called coagution value .   therefroe higher is the coagulatings power of effective ion, smaller will be the coagultion value of the electrolyte.  the ability of an ion to bring about coagulation of a given colloid depends upon :
