14.15b 6th ed

14.15 Write the half-reactions and devise a galvanic cell (write a cell diagram) to study each of the following reactions:
(b) H+(aq) + OH-(aq) --> H2O(l), the Brønsted neutralization reaction
answer:
(b) anode: 4 OH-(aq) --> O2(g) + 2H2O(l) + 4 e-; cathode: O2(g) + 4H+(aq) + 4e- --> 2H2O(l)
Pt(s) | O2(g) | OH-(aq) || H+(aq) | O2(g) | Pt(s)

Why is the H2O omitted from the cell diagram?

Water is always omitted from cell diagrams.
