Reduction or oxidation?
« on: October 09, 2015, 07:20:17 AM »
A hydrogen electrode is immersed in an acetic acid soln.  This electrode is connected by an external circuit to an iron nail dipping into 0.10 M FeCl2. If the Ecell is found to be 0.24V , what is the pH of the acetic acid soln?


I was only asking this whether H2 under go reduction or oxidation? Is there some sort of clue??

Does it matter?

yes beacuase I need to apply the nerst equation for it


E= E° -  0.0257/n ln x/y


where by knowing x and y i can easy compute for H+ concentration. Also I may solve for the right sign for E°
so how to know whether what species went oxidation or reduction?
