Assertion : `Fe(OH)_(3) and As_(2)S_(3)` colloidal sols on micing fro precipitate.
Reason : `Fe(OH)_(3) and As_(2)S_(3)` combine to from precipitate of new compound.

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:
C
Correct reason. On mixing `Fe(OH)_(3)` (-ve sol) and `As_(2)S_(3)` (-ve sol) nutual coagulation occurs leading to a precepitation. No new compound is formed.
