Electroplating is an important industrial process to prevent corrosion and upvalue jewelry and cutlery (0:30). Electroplating takes place in electrolytic cells, which need an external power source (1:25). Our episode qualitatively describes electroplating using the example of a zinc spoon and silver (1:52). Quantitatively, we discuss Faraday’s law and the relationship between electric charge, current, time and Faraday’s constant first theoretically (3:41) and then with an example problem asking how much silver is being produced when applying 5.0A for 31 minutes (5:07).
Question: Electrolysis can also be used to produce or refine metals in electrometallurgy. What is the name of the electrolytic process to produce aluminum?
