Galvanic Cell

[Deborah Cheng 1F]

What exactly is a galvanic cell? I know the definition Dr. Lavelle gave in class, about it changing chemical energy to electrical energy (such as a battery) but is the main takeaway that it makes use of redox reactions?

[Julia Cheng 2J]

Yes; it uses spontaneous redox reactions to generate electrical energy.

A galvanic cell is simply the electrochemical cell that uses the transfer of energy in redox reactions, which supplies an electric current. It comprises of two half cells connected by a salt bridge, and the transfer of electrons is spontaneous. As a result, there will always be a positive voltage

[Guangyu Li 2J]

Galvanic Cell is an electrochemical device that generates electricity through the spontaneous redox reaction taking place in the cell. Cathode receives the electrons and has reduction reaction.
