I need to determine the reduction potentials of all other half-lifes using reduction potential of Zn^2+ (0.10)/Zn half-reaction. I included the data for one of the half-lives I need to find. The known reduction potential for Zn^2+/Zn is -0.79 The cathode is Cu and the anode is Fe The potential (V) for this half cell is 0.767 and it is the potential for the Ecell. The concentration of Cu(NO3)2 is 0.10M and the concentration of Fe(NO)3 is 0.10M In the Cu/Zn pairing the supposed reduction potential of Cu was 0.212. The instructions said to use this value to determine reduction potential of Fe
0 A certain half-reaction has a standard reduction potential E 'red must provide at least 0.70 V of electrical power. The cell will operate under standard conditions. Note for advanced students: assume the engineer requires this half-reaction to happen at the anode of the cell. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the minimum. Round your answer to 2 decimal places. If there is no lower limit, check the "no" box. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have? If so, check the "yes" box and calculate the maximum. Round your answer to 2 decimal places. If there is no upper limit, check the "no" box.

A standard galvanic cell is constructed in which a Cd2+ | Cd half cell acts as the cathode. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) In the external circuit, electrons flow from the Cd2+|Cd compartment to the other compartment. As the cell runs, anions will migrate from the Cd2+|Cd compartment to the other compartment. O Cd is oxidized at the cathode. The anode compartment could be I2|I. UThe cathode reaction is Cd2+ + 2e -> Cd.
Enter electrons as e". Use smallest possible integer coefficients. If a box is not needed, leave it blank. Use a table of Standard Reduction Potentials to predict if a reaction will occur between Fe metal and Cl,(g), when the two are brought in contact via standard half-cells in a voltaic cell. If a reaction will occur, write a balanced net ionic equation for the reaction, assuming that the product ions are in aqueous solution. If no reaction will occur, leave all boxes blank.
One half-cell in a voltaic cell is constructed from a silver wire dipped into a AgNO3 solution of unknown concentration. The other half-cell consists of zinc electrode in a 1.0 M solution of Zn(N03)2. A potential of 1.48 V is measured for this cell. Calculate for the concentration of Ag+(aq).
