The Voltaic Pile was invented by Alessandro Volta in 1800. Volta demonstrated that when metals and chemicals come into contact with each other they can produce an electrical current. In his research, Volta placed together several pairs of alternating copper (or silver) and zinc discs separated by cloth and soaked the cloth in brine (salt water) to increase conductivity. An electrical current was produced in this fashion and was the first chemical battery. On March 20, 1800, Volta wrote to the London Royal Society the technique for producing electrical effect via his piles. William Nicholson and Anthony Carlisle discovered electrolysis of water with the Voltaic pile. Humphry Davy showed electricity from Voltaic Piles were caused by the chemical reaction (not differentials between metals theretofore believe). Davy also used the Voltaic pile to decompose and discover materials.
Luigi GalvaniLuigi Galvani ( September 9 1737 December 4 1798) was an Italian physician and physicist who lived and died in Bologna. Dissecting a frog at a table where he had been conducting experiments with static electricity, Galvani touched an exposed sciatic nerve
Galvanic cellThe Galvanic cell named after Luigi Galvani, consists of two metals connected by an electrolyte which forms a salt bridge between the metals. In 1780, Luigi Galvani discovered that when two different metals (copper and zinc for example) were connected tog
Discoveries of the chemical elementsThe story of the discoveries of the chemical elements is presented here in chronological order. The elements are listed generally in the order in which they were first isolated as the pure element, rather than as a compound (some such as boron were known
