a) cathode, cathode
b) anode, anode
c) anode, cathode
d) cathode, anode
Concept #2: Although electrolytic cells have the same major components as galvanic cells, there are some key differences
Example #2: Which of the following is true about an electrolytic cell?
a) Has a positive cathode
b) Has no salt bridge
c) Cathode plates out
d) Has a negative anode
Concept #3: An electrolytic cell uses non-spontaneous redox reactions.
Example #3: If the standard cell potential Eºcell for the given redox reaction is – 0.54 V, which of the following statements is true? z
Zn2+ (aq) + Ni (s) Zn (s) + Ni2+(aq)
a) The redox reaction will have an equilibrium constant value that is greater than 1.
b) The redox reaction will produce electricity.
c) The redox reaction will have an equilibrium constant value that is less than 1.
d) The reaction quotient will be less than the equilibrium constant.
