QuestionIdentify the ONE FALSE statement regarding the electrochemical cell Co( s)CoSO4(1.00M)Fe(NO3)3(1.00M),Fe(NO3)2(1.00M)Pt( s)\mathrm{Co}(\mathrm{~s})\left|\mathrm{CoSO}_{4}(1.00 \mathrm{M}) \| \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{3}(1.00 \mathrm{M}), \mathrm{Fe}\left(\mathrm{NO}_{3}\right)_{2}(1.00 \mathrm{M})\right| \mathrm{Pt}(\mathrm{~s}) for which Ecell =+1.05 V\mathrm{E}_{\text {cell }}=+1.05 \mathrm{~V}. The cell contains a KCl salt bridge. Increasing the concentration of CoSO4(aq)\mathrm{CoSO}_{4}(\mathrm{aq}) reduces the cell potential. K+\mathrm{K}^{+}ions from the salt bridge migrate to the cathode. Pt(s)\mathrm{Pt}(\mathrm{s}) is the cathode. Fe3+\mathrm{Fe}^{3+} ions migrate toward the Pt(s)\mathrm{Pt}(\mathrm{s}) electrode. The Co2+\mathrm{Co}^{2+} concentration decreases during operation of the cell.

Studdy Solution
During the operation of the cell, Co2+\mathrm{Co}^{2+} is produced at the anode, so its concentration increases, not decreases. However, this statement is not the false statement we identified in STEP_2.
The false statement is:
"Increasing the concentration of CoSO4(aq)\mathrm{CoSO}_{4}(\mathrm{aq}) reduces the cell potential."
