4. In a voltaic cell, electrical energy will be produced when
1) Only oxidation occurs 3) Both oxidation and reduction occur
2) Only reduction occurs 4) Neither oxidation nor reduction occurs
5. A voltaic cell differs from an electrolytic cell in that a voltaic cell uses
1) Spontaneous redox reaction to produce electrical energy
2) Non-spontaneous redox reaction to produce electrical energy
3) Electrical energy to force a spontaneous redox reaction to occur
4) Electrical energy to force a non-spontaneous redox reaction to occur
6. The redox reaction that occurs during the operation of a battery is best described as
1) Non-spontaneous and occurring in a chemical (voltaic) cell
2) Spontaneous and occurring in a chemical (voltaic) cell
3) Non-spontaneous and occurring in an electrolytic cell
4) Spontaneous and occurring in an electrolytic cell
7. Which is true of a voltaic cell but not of an electrolytic cell?
1) Voltaic cells involve redox reaction
2) Voltaic cells uses external energy source
3) Voltaic cell is use in the electroplating of metallic surfaces
4) Voltaic cells contains a salt bridge
8. An electrolytic cell is different from a voltaic cell because in an electrolytic cell
1) A redox reaction occurs
2) A spontaneous reaction occurs
3) An electrical current is produced
4) An electrical current causes a chemical reaction
9. Which is true of the anode in any electrochemical cell?
1) The anode is the site for oxidation
2) The anode is the site for reduction
3) The anode is the site for both oxidation and reduction
4) The anode is the site where protons are lost and gained
10. Which is true of the cathode in all electrochemical cells?
1) The cathode is the site for oxidation
2) The cathode is the site for reduction
3) The cathode is the site for both oxidation and reduction
4) The cathode is the site where protons are lost and gained
