A.2. Table of Electrode Potentials In Table A.1, you should have a value for Eed or Exid for each of the electrode systems you have studied. Remembering that for any electrode system, Ed=-Exid, you can find the value for Ed for each system. List those potentials in the left column of the table below, in order of decreasing (more negative) value. EO reduction (Eº Ag+,Ag = 0.00 V) Electrode reaction in reduction (Eº E reduction H.H₂ = 0.00 V) The electrode potentials you have determined are based on setting E = 0.00 V. The usual convention in Agt.Ag electrochemistry is to set EH¹,H₂ = 0.00 volts, under which conditions E "Ag, Ag red = +0.80 V. Convert from one base to the other by adding 0.80 volts to each of the electrode potentials in the first column, and enter these values in the third column of the table. Why are the values of Ed on the two bases related to each other in such a simple way?
