Bunsen cell
Encyclopedia : B : BU : BUN : Bunsen cell
The Bunsen cell, is a zinc-carbon electric cell (colloquially called "battery") composed of a zinc electrode in dilute sulphuric acid separated by a porous diaphragm from a carbon (graphite) electrode in nitric or chromic acid.
The cell is named after its inventor, German chemist Robert Wilhelm Bunsen, who improved upon the Grove cell by replacing Grove's platinum electrode with a much cheaper gas retort carbon. This battery, like Grove's, emitted noxious fumes.
Bunsen used this cell to extract metals from their salts by electrolysis, enabling him to isolate metallic magnesium for the first time.
