Question

ADVANCED MATERIAL Picking a reduction of Gaddation that will make a galvanic cell work A certain half-reaction has a standard reduction potential Ed -0.35 V. An engineer proposes using this half-reaction at the anode of a galvanic cell that must provide at least 0.90 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? yes, there is a minimum. E - Oy s, check the res box and calce the minimum. Round your answer to 2 decimal places. If there is n ow mit, check the box x 5 ? ves, there is a maximum v Is there a maximum standard reduction potential that the harreaction used at the cathede 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 now imit, check the new By using the information in the ALEKS Datatab, write a balanced equation describing a half reaction that could be used at the cathode of this Noter write the half reaction as it would actually occur at the cathode.
