Can we determine the presence of different ions and their concentration ratio in the electrolyte according to the cyclic voltammetry curve obtained ?

22 October 2019 0 4K Report

I have this electrolyte where I added 50 mM SnSO4 and 100 mM sodium gluconate in deionised water. I want to find out from the CV curve whether i can comment on the presence of Sn2+ and Sn4+ ions as i can see multiple reduction peaks. Furthermore, can the ionic ratio be calculated from the relative peak areas ?

The scan started from +0.4 V into negative direction till -2.0V and then reversed.
