Hi, if anyone can give me help for any part of the question that would be great! I know how to draw the cell diagram, but am not sure what the half-reactions would be.... Here is the question:
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.
