Consider the standard galvanic cell based on the following

Chapter 18, Problem 117

(choose chapter or problem)

Consider the standard galvanic cell based on the following halfreactions: 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)4 2(aq).] c. NaCl(s) is added to the silver half-cell compartment. [Hint: Ag reacts with Cl to form AgCl(s).] d. Water is added to both half-cell compartments until the volume of solution is doubled. e. The silver electrode is replaced with a platinum electrode. 11
