I am doing a multiple choice question which asks which equation best describes the overall redox reaction occurring in the electrolysis of 1.0M tin(IV) chloride.
I have narrowed it down to these two:
Sn4+(aq) + 2H2O(l) --> Sn(s) +O2(g) + 4H+(aq)
Sn4+ (aq)+ 2Cl-(aq) --> Sn(s) +Cl2(g)
I first thought it was the first equation but since the concentration of Cl- ions will be 4.0M, would they preferentially oxidise instead of water?
