Question

A certain half-reaction has a standard reduction potential 0.11 V. An engineer proposes using this half-reaction at the cathode of a galvanic cell that must provide at least 1.20 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 cathode of the cell Is there a minimum standard reduction potential that the half-reaction used at the anode of this cell can have? Ered-Ov O yes, there is a minimum . 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. no minimum Is there a maximum standard reduction potential that the half-reaction used at the anode of this cell can have? yes, there is a maximum 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. no maximum By using the information in the ALEKS Data tab, write a balanced equation describing a half reaction that could be used at the anode of this cell Note: write the half reaction as it would actually occur at the anode.

Explanation / Answer

no minimum,

because, E0cell = E0cathode - E0anode

              1.2   = -0.11 - (x)

                x = -1.31 V

yes,there is a maximum , E0red = -1.31 v

anode, that could be used.

the E0anode, mustbe at least equal to or lessthan than -1.31 v.

half-reaction :  

Ti2+ + 2e Ti(s) E0 = 1.63 v
