Galvanic Cells

Currently, it is not possible the potential difference between a strip of metal and a solution where the metal is dipped in. This arrangement is known as a galvanic cell and the situation can be represented as an oxidation-reduction (redox) reaction equation. A typical call consists of two strips of metal (one zinc and the other copper) and they are usually dipped in a solution containing salt from the corresponding metal. The two sides are separated by a porous barriers; this is because it avoids the two mixers from mixing at a fast rate but still allows the ions to diffuse from both sides. The set up can be seen in the picture.

The Main Idea

Oxidation – reduction reactions are very useful when it comes to calculating electrical energy in batteries. A basic electrochemical cell can be made with copper and zinc metals and solutions of their sulfates. During this reaction, the electrons from the zinc will be transferred to the copper through an electric conducting path (electric current). The more basic version of a galvanic cell is called an electrochemical cell; the difference is that galvanic cells can generate electric current.
