#14.13 Part D (Sixth Edition)

Postby gabbym » Wed Feb 27, 2019 2:19 pm

Can someone explain to me how you know which compounds to use for the reduction reactions? For example, #14.13 Part D asks you to write the half-reactions, the balanced equation for the cell reaction, and the cell diagram for each of the following skeletal equations:
Au+(aq) --> Au(s) + Au3+(aq)
The correct half reactions are Au+ --> Au, and Au ---> Au3+.
I understand the first one, but why wouldn't the second one by Au+ ---> Au3+?
Someone help please

I'm stuck on the same problem, I think it might have to do with adding the two half reactions together at the end and having the final equation be balanced, but I'm not sure. If someone could explain this that would be great!
