What is Hardy Schulze Rule?

Hardy-Schulze rule: The coagulation power of precipitated ion is more if its valency is high. For example, coagulation power series of Al3+, Na+ and Ba2+ is Al3+ > Ba2+ > Na+.

In a sentence this rule state as “Greater is the valency of the oppositely charged ion of the electrolyte being added, the faster is the coagulation”.
