Galvanic Cells

Postby Dayna Pham 1I » Wed Feb 20, 2019 4:56 pm

Hello!
I can't seem to wrap my head around the concept of galvanic cells. In class today, we learned that galvanic cells change chemical energy, but what exactly is a galvanic cell? When "cells" are mentioned, am I suppose to think of biological cells or just pockets of space? I'm having trouble visualizing this.

Hi Dayna!

So the galvanic cell is that diagram Lavelle drew on the board. It's the basis for a battery. It's neither a biological cell or a pocket of space.

Hope that helps!

So just to clarify, does a galvanic cell involve the cathode and anode?

Yes, galvanic cells include both the cathode and anode.

It's basically just the drawing on the board that Lavelle had where a spontaneous redox reaction (the cathode and the anode) converts chemical energy into electrical energy through the transfers of electrons

A battery is just a collection of galvanic cells joined in a series and each galvanic cell has an anode and a cathode.

Could someone explain the purpose and importance of having a salt bridge between the galvanic cells?

The purpose of a salt bridge is not to move electrons from the electrolyte, rather it's to maintain charge balance because the electrons are moving from one-half cell to the other. The electrons flow from the anode to the cathode.
