Assertion: van method is used to prepare...

Assertion: van method is used to prepare ultrapure samples of some metals.
Reason: It involves reaction of `CO` with metals to form volatile carbony,s which decompose on heating to give pure metal.

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 but 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
van Arkel method involves use of `I_(2)` to from volatile iodide of metals which on decomposition gives pure metals.
