Electrochemical Concepts

What is a galvanic cell?

• A tool for generating solar power

• A type of battery that stores electrical energy

• An electrochemical cell that generates electrical energy from spontaneous redox reactions.

• A device used to measure electrical resistance

Explain the electrolysis process.

• The electrolysis process involves the decomposition of an electrolyte into its constituent elements using an electric current.

• Electrolysis is a process that involves the use of mechanical energy to separate elements

• During electrolysis, elements are combined to form new compounds

• The electrolysis process does not require the use of an electric current

What are the anode and cathode reactions in an electrochemical cell?

• Anode reaction: Reduction, Cathode reaction: Oxidation

• Anode reaction: Combustion, Cathode reaction: Evaporation

• Anode reaction: Neutralization, Cathode reaction: Activation

• Anode reaction: Oxidation, Cathode reaction: Reduction

How do electrolyte solutions contribute to the functioning of electrochemical cells?

• Electrolyte solutions generate heat to power electrochemical cells

• Electrolyte solutions repel electrons, preventing electric current flow in electrochemical cells

• Electrolyte solutions absorb light energy in electrochemical cells

• Electrolyte solutions provide ions that facilitate the transfer of electrons between electrodes, allowing the flow of electric current in electrochemical cells.

Discuss the differences between an electrolytic cell and a galvanic cell.

• An electrolytic cell generates electrical energy from a spontaneous chemical reaction.

• A galvanic cell requires an external voltage source to drive a non-spontaneous chemical reaction.

• An electrolytic cell requires an external voltage source to drive a non-spontaneous chemical reaction, while a galvanic cell generates electrical energy from a spontaneous chemical reaction.

• An electrolytic cell converts electrical energy into chemical energy.
