Options

A. The magnitude of the charge on the ion alone
B. Size of the ion alone
C. The sign of charge on the ion alone
D. Both magnitude and sign of the charge on the ion

Answer

D

Explanation

Coagulation of colloidal solution by using an depends on the charge present (positive or negative) colloidal particles as well as on its size.
Coagulating power of an electrolyte depends magnitude of charge present on effective ion of electrolyte
