Refer to the following standard reduction half-cell potentials at 25∘C:
VO2+(aq)+Ni2+(aq)2H+(aq)++2e−e−→ →Ni(s)VO2+(aq) +H2O(l)E∘=−0.23V E∘=0.99V
An electrochemical cell is based on these two half-reactions: Oxidation:Reduction:
Ni(s)VO2+(aq,0.083M)+2H+(aq,1.1M)+e −→→Ni2+(aq,2.5M)+2e−VO2+(aq,2.5M)+H 2O(l)
Calculate the cell potential under these nonstandard concentrations.
Express the cell potential to two decimal places and include the appropriate units.
