Questions and Answers

What is electrochemistry?

Electrochemistry is the branch of science that deals with the conversion of chemical energy into electrical energy.

What is an electrochemical cell?

An electrochemical cell is a device that converts chemical energy into electrical energy through a chemical reaction.

What are the two compartments in an electrochemical cell?

The two compartments in an electrochemical cell are the cathode and the anode.
