Problem

Use the data below to determine which statement is true of the voltaic cell illustrated here.
The figure shows a voltaic cell. It contains 2 beakers. One beaker is filled with 1 molar solution of Sn 2 plus and the other is filled with 1 molar solution of Ag plus. A plate of solid Sn is lowered into the first beaker, and a plate of solid Ag is lowered into the other beaker. There is also a salt bridge between the beakers and plates are connected to each other.


Ag+(aq) + e  →  Ag(s) E˚ = 0.80 V; Sn2+(aq) + 2 e  →  Sn(s), E˚ = –0.14 V
a) Sn is the anode; Ag is the cathode; electrons flow from left to right.
b) Sn is the cathode; Ag is the anode; electrons flow from left to right.
c) Sn is the anode; Ag is the cathode; electrons flow from right to left.
d) Sn is the cathode; Ag is the anode; electrons flow from right to left.
