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.
coagultion value ` propto = 1/("coagulating power")`
the coagulation values of differnt electrolytes are different . this behavious can be easily uderstood by Harby - schulze rule which states.
the greater is the valency of the effective ion grreater is its coagulating power,"
which one had the highest coagulating powe?

A

`K^(+)`

B

`Ca^(2+)`

C

`Al^(3+)`

D

`Sn^(4+)`
