1) Now construct a different electrochemical cell. You put a zinc metal anode in contact with a 0.052 M solution of zinc nitrate and a silver cathode in contact with a 0.0042 M solution of silver(I) nitrate. You connect the electrodes with a wire and connect the solutions with a salt bridge. Will the measured voltage across the electrochemical cell be equal to E ?
A. Yes, by definition, the operation of an electrochemical cell is under standard conditions
B. No, the concentrations of dissolved cation are not 1 M.
C. Impossible to tell from the information given.
X D. Yes, the concentrations of dissolved cation are neither 1 M but they are identical to each other, so E does NOT equal E .

2) Consider the electrochemical cell described in question 2. Will the electric potential E (i.e. the voltage) measured across the cell at the moment the reaction begins be equal to the standard potential E ?
X A. Yes. Measured voltages in an electrochemical cell equal E
B. No. E equals E when the concentrations of cation are identical as long as the stoichiometric coefficients are also identical, and that is not true here.
C. No. E would equals E when the concentrations of cation are 1 M and these concentrations are not 1 M.
