What experimental methods did Arrhenius use?
My approach was fundamentally empirical and quantitative. To develop the theory of ionic dissociation, I relied heavily on the precise measurement of electrical conductivity in solutions. By carefully observing how the electrical resistance of water changed when various solutes were added, I could infer the extent to which these solutes were breaking down into charged particles. This involved meticulous experimentation and the application of mathematical relationships to the observed data. The quantitative data consistently pointed towards a physical process of molecular splitting, rather than purely chemical reactions in the traditional sense.
