A galvanic (voltaic) cell consists of an electrode composed of chromium in a 1.0 M chromium(II) ion solution and another electrode composed of copper in a 1.0 M copper(II) ion solution, connected by a salt bridge. Calculate the standard potential for this cell at 25 °C. For standard potentials: https://sites.google.com/site/chempendix/potentials

Solution

Ther is not any Cu+ in this cell . you shoud n t introduce Cu + in soloution. Cu 2+ + 2e == Cu Ni ==Ni 2+ + 2e reaction: Cu 2+ + Ni == Cu + Ni 2+ E cell = 0.34 - (-0.26)=0.6 V= 600 mV
