Consider the standard galvanic cell based on the following half reactions Cu2+ + 2e- → Cu Ag+ + e- → Ag The electrodes in this cell are Ag(s) and Cu(s). Does the cell potential increase, decrease, or remain the same when the following changes occur to the standard cell?
a. CuSO4(s) is added to the copper half cell compartment (assume no volume change).
b. NH3(aq) is added to the copper half cell compartment. [Hint: Cu2+ reacts with NH3 to form Cu(NH3)42+(aq).]
c. NaCl(s) is added to the silver half cell compartment. [Hint: Ag+ reacts with Cl2 to form AgCl(s).]
