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 :

Options

  1. ABoth Statement I and Statement II are true
  2. BStatement I is false but Statement II is true
  3. CStatement I is true but Statement II is false
  4. DBoth Statement I and Statement II are false

Correct answer

C. Statement I is true but Statement II is false

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.
