A galvanic (voltaic) cell consists of an inert platinum electrode in a solution containing 1.0 M chromium(III) ion and 1.0 M chromium(II) ion, and another inert platinum electrode in a solution containing 1.0 M cobalt(III) ion and 1.0 M cobalt(II) ion, connected by a salt bridge. Calculate the standard potential for this cell at 25°C. Standard reduction potentials can be found in the standard reduction potentials table.
