Question

you observed that very little corrosion occurred on the nail immersed in NaOH(aq) solution. This observation is difficult to explain from an electrochemistry perspective since electrochemistry principles predict a spontaneous reaction that should cause corrosion. Explain why there was no corrosion on this nail from an equilibrium perspective using the half-reaction shown below:

O2(g)+ 2 H2O(l) + 4 e- --> 4 OH-(aq)

i cant figure out how to explain the reaction in the terms they want i desperatly need help.
