Svante Arrhenius

Svante Arrhenius, a Swedish scientist, discovered the Greenhouse effect, made theories on acids, bases, and reactions, and is credited with being one of the founders of physical chemistry.

Born February 19, 1859

1889

Finishes ArrheniusEquation

Using the equation created by J. H. van 't Hoff, Svante interpreted the equation and supported it with physical evidense. The simple, but accurate, equation calculates the rates of reactions in substanes at certain temperatures.

While many scientists thought climate change depended on water vapor levels, Arrhenius realised that CO2 levels affected temperature much more. He did many experiments on CO2 levels and found that it, along with other gases, was the leading cause of climate change. He also found that changes in CO2 levels could be largely affected by humans and he predicted that the Earth would get warmer in the future. He was right.

In 1903 Svante Arrhenius received the Nobel Prize in Chemsitry for his work with substances and reactions, and for his thoeries and equations. He was the first Swedish scientist to be awarded the Nobel Prize in Chemistry.

Fom 1901 to his death he was a high member on the Nobel Committee of Physics and a member of the Nobel Committee of Chemistry. To this day he is considered a physicist and a chemist.

Fun Fact: During his time as a member of the Nobel Committee. Svante Arrhenius may or may not have used his power to help his friends get prizes and deter his enemies from the awards.

Svante Arrhenius states that acids are substances that, in water, yield ions (And at least one hydrogen ion). Bases are substances that ionize in water to produce hydroxide ions. His definition of acids and bases is still widely accepted and used today.

Arrhenius worked with many scientist including J. H. van 't Hoff. He also based a lot of his work on the findings of Michael Faraday, John Tyndall, and many others.
