Statement 1: For the coagulation of sols carrying a positive charge, ions are more efficient than or ions. Statement 2: This follows the Hardy–Schulze rule.

(A)Assertion is True, Reason is True; Reason is correct explanation for AssertionCorrect
(B)Assertion is True, Reason is True; Reason is not correct explanation for Assertion
(C)Assertion is True, Reason is False
(D)Assertion is False, Reason is True

Answer: (A)

Solution

A positively charged sol is coagulated by anions, and (charge ) is indeed a more efficient coagulant than (charge ) or (charge ), so Statement 1 is true.
