Question #114358
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 and is genuinely interested why does occurs. Thanks guys have a great day

Your question is not clear

A voltaic cell is an electrochemical cell that uses a chemical reaction to produce electrical energy.

When HCl and NH3 is used there is a change in pH of the solution so the H+ concentration changes that may give an effect on the cell reaction and EDTA is a masking and trapping agent it also can give a change in the potential.
