Chemistry Question on Classification of Colloids
On which of the following properties does the coagulating power of an ion depend ?
A
The sign of charge on the ion alone
B
The magnitude of the charge on the ion alone
C
Both magnitude and sign of the charge on the ion
D
Size of the ion alone
Answer
Both magnitude and sign of the charge on the ion
Explanation
Solution
??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.
