... by personalities, politics, and prejudice ces. One of the best illustrations of the often bumpy path of the advancement of scientific knowledge is the story of Swedish chemist Svante Arrhenius. When Arrhenius henius began his doctorate at the University of Uppsala around 1880, he chose to study the passage of electricity through solutions. This was a problem that had baffled scientists for ... 1883, and I could not s leep that night until I had worked through the whole problem." His idea was that ions were responsible for conducting electricity through a solution. B ack at Uppsa]a, Arrh...

... 2 sons and 2 daughters. His family later moved to Uppsala before he moved on to go to school in Stockholm. Arrhenius began his work with chemistry with the chemist Edlund. These two worked on electromotive force measurements in spark discharges which helped Arrhenius develop his thesis. From this thesis he was able to deduce that electrolytes come apart into positive and negative ions ... became a professor teaching physics in Stockholm. Ostwald and van't Hoff are two other founding fathers of chemistry that Arrhenius earned the respect of. Arrhenius had to turn down a job that Ostwald ...

... as acid-base interactions comes from the wide acceptance of the Lewis definition of acids and bases, which supplanted both the earlier Bronsted-Lowry concept and the first definition--the Arrhenius model. Arrhenius first defined acids as proton (H) producers in aqueous solution and bases as hydroxide (OH) producers. Although this model is intuitively correct, it is limited to substances that include proton ... through use of buffers. Learning how buffers work and what their limitations are can help us to better understand our physiology. TERMS Acid - A compound which yields hydrogen ion...

... litmus paper turns red in acidic solutions and blue in alkaline solutions. There are three theories that identify a singular characteristic which defines an acid and a base: the Arrhenius theory, for which the Swedish chemist Svante Arrhenius was awarded the 1903 Nobel Prize in chemistry; the BrÖnsted-Lowry, or proton donor, theory, advanced in 1923; and the Lewis, or electron-pair ... ...
