Calculate the values of Delta G and Ecell for the following reaction, label the half reactions as anode and cathode. 2Ag(s) + Cu2+ (aq) > 2 Ag+ (aq) + Cu(s) * My main question lies in which is cathode and anode...it seems that the Ag half reaction (2Ag(s) > 2Ag+ +2e-) signifies Ag(s) loosing electrons causing the positive reactant, this leads me to think loss of electrons/this is the oxidation half reaction, therefore Ag(s) is the reduction agent and anode...
