I got the diagram from my teacher, but I’m confused on what
the Pt(s) is and why there is an Sn+4(aq), Sn+2(aq), MnO-4(aq) and
a Mn+2(aq). Why are there different charges of the same ion on each
side separated by a comma? And a H+ as well?
Also, I need help writing down the balanced equation for the
overall cell reaction.
Thanks! (will rate!)
