Question

Cathode reaction of iron in rusting process

Answer 1

Answer:

$\huge {\mathcal{\purple{h}\green{e}\pink{yaa}\blue{!}}}$

Explanation:

In the corrosion process, iron metal acts as the anode in a galvanic cell and is oxidized to Fe2+; oxygen is reduced to water at the cathode. The relevant reactions are as follows: at cathode: O2(g)+4H+(aq)+4e−→2H2O(l)E°=1.23V.
