JEE Main 2025 — 22 January, Evening Shift — Question 41
Given below are two statements : one is labelled as Statement I and the other is labelled as Statement II :
Statement (I) : Corrosion is an electrochemical phenomenon in which pure metal acts as an anode and impure metal as a cathode.
Statement (II) : The rate of corrosion is more in alkaline medium than in acidic medium.
In the light of the above statements, choose the correct answer from the options given below :
- Option A:
Both Statement I and Statement II are false
- Option B:
Statement I is false but Statement II is true
- Option C:
Both Statement I and Statement II are true
- Option D:Correct
Statement I is true but Statement II is false
Answer: D
Step-by-step solution
Statement I Corrosion is an example of electrochemical phenomenon In which pure metal act as
anode and impure metal (rusted metal) act as cathode.
Statement II Corrosion is more favourable in acid medium than alkaline so rate of corrosion is high
is acid medium then alkaline.
