What is the effect of the exchange of ligands in the electrolyte on the Electrode Potential in a voltaic cell?
So I am a high-school student and I am researching voltaic cells, and the effect of ligand substitution has on them. Basically, my experiment is that I add some designated solutions to Copper sulphate (I added EDTA, HCl and Ammonia), and then use this new solution to make a voltaic cell using a copper strip. This changes the potential difference of the cell. But I have no idea what this happens. On the book it mentioned about complexation. Anyways, any help would be appreciated. Thanks
