A standard galvanic cell is constructed with I2|I- and Mg2+|Mg half cell compartments connected by a salt bridge. Which of the following statements are correct? Hint: Refer to a table of standard reduction potentials. (Choose all that apply.) The anode compartment is the Mg2+|Mg compartment. Mg2+ is reduced at the cathode. As the cell runs, anions will migrate from the I2|I- compartment to the Mg2+|Mg compartment. In the external circuit, electrons flow from the I2|I- compartment to the Mg2+|Mg compartment. The anode compartment is the I2|I- compartment.
Consider a voltaic cell comprised of Zn/Zn2+ at one electrode and Fe2*/Fe3+ at the other electrode at standard conditions. Electrons will flow from the [ Select ] , which is the [ Select ] , and the cations in the salt bridge will flow towards the [Select ] . You may find a list of standard reduction potentials useful.
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.
