I understand that now, absolutely. After a bit more thinking (and watching a diploma review video) I realized that the given half reaction is necessary for all rusting examples in this level of chemistry; something I had not been explicitly taught. So when that half-reaction is applied to the...

I have since been explained the answer thusly: "Corrosion is the result of a redox reaction. Shown below is the reduction half-reaction. Now if we add more hydroxide ions, the reaction will shift towards the left, correct? This will impede the reduction half-reaction – it will not occur to any...

epenguin: Iron giveth and hydroxide taketh thee electrons so to speak, yes. I've not yet had any lessons concerning electron concentration that could apply, no, it was more of an intuitive thought. Certainly from an electrochemical perspective I can describe the redox of iron in NaOH, but from...

To Be Clear: The reaction of iron in NaOH is spontaneous, I know. If I could change the title I would.

The question asks: Recall that you observed very little corrosion occurring on the iron 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...

Excellent! That helped it to all click, thank you. :)
