Assertion: `Fe(OH)_(3)` and `As_(2)S_(3)` colloidal sol on mixing precipitates.
Reason: `Fe_(OH)_(3)` and `As_(2)S_(3)` combine and form new compistion precipate.

A

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

B

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

C

If assertion is true but reason is false.

D

If assertion is false but reason is true.

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 cause precipitation.
