All That Glitters

Mass Bradley asked: Electroplating. What is it good for?
Thank you for the question, Bradley: Electroplating is a process by which a layer of one type of metal is deposited on an object made of another type of metal, thereby changing the surface properties of that item.

Many items are electroplated, including metal utensils, jewelry, car parts, etc.

Benefits of electroplating include making the item stronger or better looking. However, there are many disadvantages because it uses large quantities of chemicals and generates waste that can be hazardous to the environment.
