Question

Which of the following properties does the coagulating power of an ion depend on?

• A. Both the magnitude and the 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 ion alone

Answer 1

The correct option is A Both the magnitude and the sign of the charge on the ion


Coagulation of a 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 the effective ion of the electrolyte.
