Asked: March 31, 2021In: Corrosion

GATE MT 2021 Q52. At 25 °C, iron corrodes in a deaerated acid of pH 3 with a corrosion current density of 4 µA cm-2. The corrosion potential (V) is: (round off to 2 decimal places). Given: βc = 0.1 V per decade of current density Exchange current density of hydrogen on iron surface = 10-9 A cm-2 R = 8.314 J mol-1 K-1, F = 96500 C mol-1All potentials are with reference to standard hydrogen electrode.
