Understanding Electrolytic and Voltaic Cells

What is another name for a voltaic cell?

• Photovoltaic cell

• Galvanic cell

• Electrolytic cell

• Fuel cell

In an electrolytic cell, what type of energy is converted into chemical energy?

• Electrical energy

• Mechanical energy

• Thermal energy

• Nuclear energy

What is the main difference between a voltaic cell and an electrolytic cell?

• Voltaic cells require a battery, while electrolytic cells do not.

• Voltaic cells convert chemical energy to electrical energy, while electrolytic cells do the opposite.

• Voltaic cells use the same metals, while electrolytic cells use different metals.

• Voltaic cells are used in electrolysis, while electrolytic cells are not.

What must be true about the metal plates used in a simple voltaic cell?

• They must be the same metal.

• They must be non-metallic.

• They must be made of copper.

• They must be different metals.

In a voltaic cell, which metal becomes the negative terminal?

• The metal with the higher density

• The metal lower in the electrochemical series

• The metal with the larger surface area

• The metal higher in the electrochemical series

What happens to the electrons released by zinc in a voltaic cell?

• They are absorbed by the negative ions in the electrolyte.

• They are absorbed by the positive ions in the electrolyte.

• They are absorbed by the surrounding air.

• They are absorbed by copper.

In a voltaic cell, what is the negative electrode called?

• Terminal

• Electrolyte

• Anode

• Cathode

Where does oxidation occur in a voltaic cell?

• At the cathode

• At the anode

• In the electrolyte

• In the external circuit

What is the role of the electrolyte in a voltaic cell?

• To provide a medium for electron flow

• To act as a battery

• To insulate the electrodes

• To prevent oxidation

In an electrolytic cell, where does reduction occur?

• At the anode

• At the cathode

• In the electrolyte

• In the external circuit
