PP005 - Zinc electroplating
Electroplating is an important industrial application of electrolysis and is studied in many pre-16 and post-16 courses. Electroplating processes often involve coating a metal object with another metal to protect or enhance the surface properties of the object. This small-scale activity provides a simple method for observing electroplating in action and is a safer alternative to methods which use nickel salts.
