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 :A.

1.	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 :A. Its sizeB. The magnitude of its charge onlyC. The sign of its charge onlyD. The sign of its charge
Answer» Correct Answer - D The ability of an ion to bring about coagulation fo a given colloid depend upon both the magnitude and sign of its charge.
