Assertion : A colloidal sol of Al(OH)(3)...

Assertion : A colloidal sol of `Al(OH)_(3)` is more readly coagulated by 0.1 M NaCl than by `0.1M Na_(2)SO_(4).`
Reason : The coagulating power of an electrolyte is related to the concentration of the active ions.

A

If both assertion and reason are correct and reason is correct explanation for assertion.

B

If both assertion and reason are correct but reason is not correct explanation for assertion.

C

If assertion is correct but reason is incorrect.

D

If assertion and reason both are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
D
Correct assertion. A colloidal sol of `Al(OH)_(3)` is more readily coagulated by 0.1 M `Na_(2)SO_(4)` then by 0.1 M NaCl solution.
Correct reason. Cogulating power of an electrolyte is related to concentration as well as charge on the active ions.
