How can two metal rods in a saline solution create electrical current? How does an ordinary battery really work? And why are some metals called noble metals? This film is about electrochemistry, which studies the relationship between chemical reactions and electric current. You will learn that an alkaline battery is an example of a galvanic cell, and that noble metals gain electrones while less noble metals give them up. You will also find out that electrolysis is a process where you use electricity to start a chemical reaction, and we will show you how substances like copper and aluminum are produced using electrolysis.
