Given below are two statements. Select the correct option (memory based jee mains shift-2 22/01/2025)
Statement-1: In corrosion pure metal acts as anode, the impure metal acts as a cathode
Statement-2: Alkaline medium increases the rate of corrosion more than in acidic medium
Both statements are incorrect
In corrosion, a metal is oxidized by loss of electrons to oxygen. Electrons released at anodic spot move through the same metal and go to another spot on the metal and reduce oxygen in the presence of \({\mathrm{H}}^{+}\) (which is believed to be available from \({\mathrm{H}}_{2}{\mathrm{CO}}_{3}\) formed due to dissolution of \({\mathrm{CO}}_{2}\) from air into water.
