What are Galvanic Cells?
This post will be an introduction to galvanic cells for QCE Chemistry.
3.2.3 – Galvanic Cells
- Understand that galvanic cells, including fuel cells, generate an electrical
the potential difference from a spontaneous redox reaction which can be
represented as cell diagrams including anode and cathode half-equations - Recognise that oxidation occurs at the negative electrode (anode) and
reduction occurs at the positive electrode (cathode) and explain how two half-cells can be connected by a salt bridge to create a voltaic cell (examples of
half-cells are Mg, Zn, Fe and Cu and their solutions of ions)
How Galvanic Cells Work?
This video goes through the workings of a galvanic cell.
An example of a galvanic cell is a fuel cell.
This video is another explanation on galvanic cells that students may find useful.
