Corrosion of iron involves\

Question

Professor PC Thomas Classes · Answer

In corrosion of iron the reactions are\ $2 \mathrm{Fe}_{(\mathrm{s})} ightarrow 2 \mathrm{Fe}^{2+}+4 \mathrm{e}^{-}$at anode\ $\mathrm{O}_{2(\mathrm{~g})}+4 \mathrm{H}^{+}+4 \mathrm{e}^{-} ightarrow 2 \mathrm{H}_{2} \mathrm{O}_{(\mathrm{l})}$ at cathode\ and $2 \mathrm{Fe}_{(\mathrm{s})}+\mathrm{O}_{2(\mathrm{~g})}+4 \mathrm{H}^{+}{ }_{(\mathrm{aq})} ightarrow 2 \mathrm{Fe}^{2+}{ }_{(\mathrm{aq})}+2 \mathrm{H}_{2} \mathrm{O}$\ as overall cell reaction\
