Assertion: For the coagulation of sols carrying positive charge, `PO_(4)^(3-)` ions are more effeciency than `SO_(4)^(2-)` or `Cl^(-)` ions.
Reason: This follows Hardy-Schulze rule.

A

If Statement-1 is True, Statement-2 is True , Statement-2 is a correct explanation for Statement-1

B

If Statement-1 is True, Statement-2 is True , Statement-2 is NOT a correct explanation for Statement-1

C

If Statement-1 is True, Statement-2 is False

D

If Statement-1 is False, Statement-2 is True

Text Solution

Verified by Experts

According to Hardly-Schedulze rule, coagulating power of an electrolyte is directly proportional to the fourth power of the valency of the ions causing coagulation.
