14.13

d) Au^(+) (aq) -> Au(s) + Au^(3+) (aq)

Why can't I use
Au+ (aq) -> Au^(3+) (aq)
for the oxidation half reaction?

When I used that I was able to get the correct overall balanced redox reaction. And when I got the cell diagram, couldn't I have placed Pt(s) on the anode side? The solutions don't have this though. Why?

I'm pretty sure both ways are right especially if you got the right overall balanced reaction. The only way that it would definitely be Au(s) is if the table of reactions shows this reaction of having Au as a solid and aqueous product.
