Cell Types

Postby Mayvera Doaran 2H » Wed Feb 03, 2016 5:21 pm

What is the difference between a galvanic cell and a voltaic cell? What other cell types should we know?

Voltaic cell is just another name for a galvanic cell. They are the same thing.

The book defines a galvanic (voltaic cell) as an electrochemical cell in which a spontaneous chemical reaction is used to generate an electric current. (569)

A galvanic cell is set up by having an anode and cathode that is connected by a thin strip of wire. Electrons are passed from the anode to the cathode, and in order to stop the build up of negative charge on the cathode and the build up of a positive charge on the anode, there needs to be a salt bridge connecting the two.

I think that we only need to know about the galvanic cell for electrochemistry.

I thought voltaic cells could have negative cell potentials whereas galvanic cells always have positive cell potentials
