In this class we will talk about the definition of electrochemical cells or galvanic cells using as an example the Daniell cell, also known as the copper and zinc cell. We will also review how to calculate the potential difference (ddp) or electromotive force (emf). To conclude, we will discuss the issue of corrosion and protection of metals in the environment, giving the example of sacrificial metals. (UPF 2012) Metal corrosion is the unwanted oxidation of a metal. It shortens the life of steel products such as bridges and automobiles, and replacing corroded metal costs a great deal of money worldwide every year. Corrosion is an electrochemical process, and the electrochemical series gives us an indication of why corrosion occurs and how it can be prevented. To protect certain metal parts, pieces of another metal can be used as a sacrificial metal. So, considering some metals with their respective standard reduction potentials: Which is the most suitable to be used as a sacrificial metal if the part to be protected is aluminum?
