A study on connection between chemistry and electricity

Renewable Energy

There is a good connection between chemistry and electricity from an ancient time. One of the great scientists named Alessandro Volta has discovered Voltaic cell in 1973. It was a great discovery for the human being. Nicholson and Carlise showed that electric current could decompose water into hydrogen and oxygen in 1800. This experiment was the most important significant experiment. This implied that the atoms of oxygen and hydrogen were associated with negative and positive electric charges. Finally it was proved that these positive and negative charges were the source of the bonding forces between them. One of the Swedish chemists named Berzelius proposed that all atoms are electrified and among them hydrogen & metals are positive and the nonmetals are negative in 1812. The applied voltage for electrolysis was thought to overpower the attraction between these opposite charges, pulling the electrified atoms apart in the form of ions. After about one hundred years later he gave a electron pair theory. Lewis could offer a significant improvement over this view of chemical bonding. Meanwhile the use of electricity as a means of bringing about chemical change continued to play a central role in the development of chemistry. Humphrey Davey prepared the first elemental sodium by electrolysis of a sodium hydroxide melt. It was left to Davey's former assistant, Michael Faraday, to show that there is a direct relation between the amount of electric charge passed through the solution and the quantity of electrolysis products. James Clerk Maxwell immediately saw this as evidence for the “molecule of electricity”, but the world would not be receptive to the concept of the electron until the end of the century.
