Expert Solution
Step 1
Dear student, since we provide one answer in a thread, we are answering number 2. Kindly re-post number 3 in another thread.
The standard reduction potentials of the half electrodes ( from a standard data table) is :
Zn2+/Zn = -0.76 V
Ag+/Ag = 0.80 V
Step 2
The above values shows that Ag+ has a higher tendency of reduction than Zn2+.
Thus, silver electrode serves as cathode, since reduction takes place at cathode and zinc electrode serves as anode.
