Alessandro Volta (1745-1827) was an Italian physicist widely known for the invention of the battery‚ but more importantly his conflicts with Luigi Galvani on their differing views about animal and chemical electricity‚ which have led to great advances in certain areas science as a whole despite areas of Galvani’s views as being incorrect. Luigi Galvani himself began using electrical means to experiment with muscular stimulation and was able to cause muscular contraction in a frog by touching its

Chemistry 1225 Lab Write-Up #13 Abstract Electrolysis is a method of using a direct electric current to drive an otherwise non-spontaneous chemical reaction. During electrolysis‚ hydrogen atoms (H2) are reduced at the cathode whereas the oxygen atoms (O2) are oxidized at the anode. There were three different solutions used in the experiment in order to have a better understanding of electrolysis reactions. From each solution‚ reaction equations were produced. The reactions could be observed from
