A gаlvаnic cell is cоmpоsed оf these two hаlf-cells, with the standard reduction potentials shown:Co2+(aq) + 2 e- Co(s)-0.28 VCr3+(aq) + 3 e- Cr(s)-0.74 VThe actual concentrations in the cell are: [Co2+] = 0.00100 M, [Cr3+]= 0.100 M. What is the potential of this galvanic cell?Hint: First calculate E°, then apply the solution concentrations of the galvanic cell using the Nernst equation.
