Arrhenius


Svante August Arrhenius was born on February 19, 1859 in Sweden. He was an important chemist, physicist and mathematician.

Arrhenius studied at Upsala Cathedral School after his family moved from the city of Vik. Started at university at 17 years. He later studied at Stockholm University.

He taught physics at the University of Stockholm Superior Technical School. In 1904, he directed the Nobel Institute of Chemistry and Physics until 1927.

During his doctorate at the University of Upsala, he studied the conductive properties of electrolytic dissolutions. According to his doctoral dissertation, substances that undergo electrolytic dissolution when dissolved dissociate to form ions. The degree of dissociation increases with the degree of solution silencing, only for weak electrolytes.

Lord Kelvin contested his work a great deal, but was supported by Jacobus Van't Hoff and Wilhelm Ostwald. Later his theory was accepted, one of the foundations of physical chemistry and electrochemistry. He was appointed dean of the Royal Institute of Technology of Stockholm in 1896.

In 1903, he received the Nobel Prize in Chemistry for his outstanding service to technology and chemistry. He developed other works in the area of ​​physicochemical such as the speed of chemical reactions and some works on immunization and astronomy.

He was a foreign member of the Royal Society in 1909. During a visit to the United States, he was awarded the first Willard Gibbs Medal in 1911. In 1914, he received the Faraday Medal. He died in Stockholm on October 2, 1927.
