What modification can you suggest for Hardy-Schulze law?

Text Solution

Verified by Experts

The correct Answer is:
According to Hardy-Schulze law, ions carrying, charge opposite to that on colloidal particles cause coagulation of the sol. This is because of neutralisation of charge on colloidal particles.
The law can be modified to add the following. If oppositely charged sols are mixed in suitable proportions to neutralise the charges of each other, coagulation of both sols takes place.
