Give the cell diagram notation of the electrochemical cell that could be used to determine experimentally the dissociation constant (Kw) of water. The standard reduction potential for

O2 + H20 + 4 e- ----> 4OH- is 0.40 V

For other possible half-reactions, see your textbook.

Calculate E° for this cell.

Also, calculate the dissociation constant at 298K.
