Assertion : A colloidal sol of `Al(OH)_(3)` is more readly coagulated

1.	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.
Answer» Correct Answer - 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.
