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 size

B

The magnitude of its charge only

C

The sign of its charge only

D

The sign of its charge

Text Solution

Verified by Experts

The correct Answer is:
D
The ability of an ion to bring about coagulation fo a given colloid depend upon both the magnitude and sign of its charge.
