On which of the following properties does the coagulating power of an ion depend ?

Options

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

Answer

A

Explanation

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