What did svante arrhenius discover bank

Svante Arrhenius (born February

Svante August Arrhenius 19 February — 2 October was a Nobel Prize -winning Swedish scientist who made discoveries in physics , chemistry and earth science. Originally he was a physicist , but he won the Nobel Prize in Chemistry , and was a founder of physical chemistry. Later in life, he turned to other scientific problems.

He was the first person to predict that emissions of carbon dioxide , from the burning of fossil fuels , would cause global warming. His early work was on the conductivity of electrolytes. It did not impress the professors, and he received a low-class degree. Later, extensions of this work would earn him the Nobel Prize in Chemistry. The most important idea in the thesis was his explanation that neither pure salts nor pure water is a conductor , but solutions of salts in water are.

Arrhenius' explanation was that in forming a solution, the salt splits up into charged particles which Michael Faraday had given the name ions many years earlier. Faraday's belief had been that ions were produced in the process of electrolysis ; Arrhenius' idea was that, even in the absence of an electric current, solutions of salts contained ions.

He proposed that chemical reactions in solution were reactions between ions. In an extension of his ionic scientific theory Arrhenius proposed definitions for acids and bases , in He believed that acids were substances which produce hydrogen ions in a solution and that bases were substances which produce hydroxide ions in a solution.

For the rest of his life, he would be a member of the Nobel Committee on Physics and a member of the Nobel Committee on Chemistry. He used his positions to arrange prizes for his friends Jacobus van't Hoff , Wilhelm Ostwald , Theodore Richards and to attempt to deny them to his enemies Paul Ehrlich , Walther Nernst. In he delivered at the University of California several lectures, to try and show the application of the methods of physical chemistry to the study of the theory of toxins and antitoxins , and which were published in under the title Immunochemistry.
