How electroplating works - Explain that Stuff

Electroplating is very similar to electrolysis (using electricity to split up a chemical solution), which is the reverse of the process by which batteries produce electric currents. All these things are examples of electrochemistry : chemical reactions caused by or producing electricity that give scientifically or industrially useful end-products.
