9.5 - Electrolysis

Electrolysis is a redox reaction and a method used to manufacture pure metal. It is also used for galvanization, silvering and chrome plating of different items. Some battery types can even be charged through the use of electrolysis.

The reaction of electrolysis is the opposite of the spontaneous reaction of a galvanic element; instead of transforming chemical energy into electrical energy, it transforms electrical energy into chemical energy. Through electrolysis the electrons are forced to go the opposite way of what they would if it was spontaneous.

The picture on the side is a picture of electroplating and came from this website.
