Electrochemical cells

Quick question. In a galvanic cell, the anode metal is being eroded away to form cations. And in the cathode cell, the cations are forming on the cathode. So wouldn't the anode be considered the reactant and cathode the product? Or are we considering the cations (in the cathode) to be the reactant?

Thanks

anodes and cathodes are in separate reactions, so neither is really the reactant or product of the other

You should look over electrochemical concepts before test day this weekend. Cations go towards the cathode but cathode is where reduction occurs so more metal is actually being formed there (ex Ag+ to Ag solid) and not cations. This stands for both galvanic and electrolytic cells, I think. Good luck!

nm.. i just found it in TPR. They are referring to the cations as the products as reactants to explain when it reaches equilibrium.

ya sorry poor wording on my part.
