oxygen, hydrogen, water

Postby Kenan Kherallah 2C » Fri Feb 22, 2019 10:14 pm

In cell diagrams in the textbook, they are much more complicated than those that we practiced in class. In many answers, I see the placement of H+ and I just want to know why (worked example 14.7 in the 6th edition shows this). Also, how do we balance this reaction (d) Pt(s) | O2 | H+(aq) || OH-(aq)| O2(g)| Pt(s)

These are the type of problems confusing me so I was wondering if anyone can help.

I know oxygen is being reduced on one side and oxidized on the other (its oxidation number is 0 in and -2 in so electrons are going from the left side to the right side). But I'm not really sure why electrons are going one way and not the other. Can someone explain this?
