5 Questions

Explain the difference between galvanic and electrolytic cells.

Galvanic cells convert chemical energy into electrical energy through spontaneous redox reactions, while electrolytic cells use electrical energy to drive non-spontaneous redox reactions.

What is the Nernst equation used for?

The Nernst equation is used to calculate the electromotive force (emf) of a galvanic cell at any concentration of reactants and products.

Define resistivity, conductivity, and molar conductivity of ionic solutions.

Resistivity (ρ) is the measure of a material's ability to resist the flow of electric current, conductivity (κ) is the measure of a material's ability to conduct electric current, and molar conductivity (L m) is the conductivity of an electrolyte solution divided by the molar concentration of the electrolyte.

What is the significance of Λ°m in the context of molar conductivity?

Λ°m represents the molar conductivity at zero concentration or infinite dilution, providing a standard value for comparison of electrolytes.

Explain the process of corrosion in the context of electrochemistry.

Corrosion is an electrochemical process in which metals deteriorate due to chemical reactions with their environment, often involving the transfer of electrons.

Test your knowledge on electrochemical cells, Nernst equation, standard potential, and ionic solutions. Learn to differentiate between galvanic and electrolytic cells and understand resistivity, conductivity, and molar conductivity of ionic solutions.
