6L.7

Postby Savannah Mance 4G » Mon Mar 02, 2020 9:53 pm

I'm so confused for like this whole problem because in the half rxns they include elements that aren't even in the entire redox rxn. Like, for part b the O2 included in the anode isn't in the whole redox rxn given. And for part a the Ag(s) wasn't in the full rxn either.

Hi there! I think for this problem, we just have to look in the Appendix for half reactions that, when we combine them, will give us the resulting equation. Hope this helps!

Hello,

When looking at the reduction half-reactions in the appendix, how do we know which one is the cathode or anode when devising the cell diagram? Thank you for the above information as well; it helped a lot!

for part a) why could we not just split up the half-reactions into Ag and Br separately?
