Cоnsider the fоllоwing hаlf-cell reаctions: Zn2+(аq) + 2e- ↔ Zn(s) Ecell = -0.76 V Cu2+(aq) + 2e- ↔ Cu(s) Ecell = +0.34 V If a cell is built by combining above two half-cells, what will be its cell potential? Hint: The half-cell with the highest positive potential gets reduced: Ecell= E(cathode) - E(anode)
