When to include OH- and H2O in cell diagrams

Postby Casey Collet 1I » Mon Feb 09, 2015 4:38 pm

When writing a cell diagram for a galvanic cell, are we supposed to leave out H2O and OH- if they are not constituting the entire reaction? Both 13.15 part c and 13.17 part b left these two compounds out of the diagram.

When I write cell diagrams, I write H+ and OH- just to be thorough but I leave out H20. Some problems require H+ or OH- to calculate pH, such as 43a.
