Assertion (A) : Cu gets readily corroded...

Assertion `(A) : Cu` gets readily corroded in acidic aqueous solution.
Reason `(R) :` Free energy of the process is positive.

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 the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Copper corrodes at negligible rates in unpolluted air, water and deaerated non-oxidizing acids. Pure copper and the high copper alloys can be considered to exhibit similar resistance to most corrosive environments. They posses excellent resistance to atmospheric environments. Corrosion is a spontaneous process for which free energy change must be negative.
