JEE Mains · Chemistry · STD 12 - 2. Electrochemistry
Given below are two statements :
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 :
- A Both Statement I and Statement II are true
- B Statement I is false but Statement II is true
- C Statement I is true but Statement II is false
- D Both Statement I and Statement II are false
Answer & Solution
Correct Answer
(C) Statement I is true but Statement II is false
Step-by-step Solution
Detailed explanation
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.
