What modification can you suggest in the Hardy Schulze law?

Explanation

According to the Hardy Schulze law, the coagulation ion has charge oppositi to that on the colloidal particles. Hence, the charge on colloidal particles is neutralized and caogulation occurs. The law can be modified to include the following:
When oppositely charged sols are mixed in proper proportions to neutralize the charges of each other, coagulation of both the sols occurs.
