Assertion(A): `Fe^(3)+` can be used for coagulation of `As_(2)S_(3)` sol.
Reason (R): `Fe_(3+)` reacts with `As_(2)S_(3)` to give `Fe_(2)S_(3.)`

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both asertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
C
`Fe(OH)_(3) and As_(2)S_(3)` are positive and negative colloids. On mixing mutual coagulation causes preceipitation.
