Electrochemical Cells and Ionic Solutions Quiz

Galvanic cells convert chemical energy into electrical energy through spontaneous redox reactions, such as a battery powering a device. Electrolytic cells, on the other hand, use electrical energy to drive non-spontaneous reactions, such as electroplating.

Resistivity (ρ) is a measure of a material's ability to resist the flow of electric current, while conductivity (κ) measures its ability to conduct electric current. Molar conductivity (Λm) quantifies the ability of a given volume of a solution to carry a charge, and these properties are critical in understanding the behavior of ionic solutions in electrochemical processes.

The Nernst equation is used to calculate the emf (electromotive force) of a galvanic cell under non-standard conditions. It relates the cell potential to the activities of the chemical species involved in the redox reaction.

<p>Primary batteries are non-rechargeable and convert chemical energy into electrical energy, while secondary batteries are rechargeable and can convert electrical energy back into chemical energy. Fuel cells utilize chemical energy from a fuel and an oxidant to produce electrical energy.</p> Signup and view all the answers
