Assertion (A) Coagulation power of `Al^(3+)` is more than `Na^(+)`.
Reason (R) Greater the valency of the flocculating ion added, greater is its power to cause precipitation (Hardy-Schulze rule) .

A

Assertion and reason both are correct and the reason is correct explanation of assertion.

B

Assertion and reason both are correct but reason does not explain assertion.

C

Assertion is correct, but reason is incorrect.

D

Assertion is incorrect, but reason is correct.

Text Solution

Verified by Experts

The correct Answer is:
A
According to Hardy-Schulze law greater the charge/valency on flocculating ion added greater will be its power to cause precipitation.
Coagulating power `prop` Valency of flocculating ion
