What compounds are used in the reaction quotient and Keq in electrochemistry? Wouldn't you have 2 reactants (the oxidizing agent and the reducing agent), and two products, the products of oxidation and reduction? For some reason, I don't think the concentrations of all four are used, but i'm not sure.
In the concentration cell example in EK chem, the concentration of Fe2+ ions in the oxidation half cell was used as the product while that of Fe2+ in the reduction half cell was used as the reactant. I don't see the logic behind it.
Secondly, since oxidation always occurs at the anode and electrons move from the less concentrated half cell to the more concentrated half cell (in concentration cells), does this mean the less concentrated solution will always be at the anode?
Thanks in advance.
