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 reason is the explaination of assertion.

B

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

C

If assertion is true but reason is false

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
Copper corrods at negligible rates in unpolluted air,water and deaerated non-oxidising acids.Pure copper and the high copper alloys can be considered to exhibit similar resitance to atmosphere environments(corossion is a spontaneous process for which free energy change must be negative.)
