CHEM 112 Lecture Notes - Lecture 1: Svante Arrhenius, Hydrofluoric Acid, Conjugate Acid
Document Summary
Svante arrhenius (1884): an arrhenius acid is a compound that contains hydrogen and reacts with water to form hydronium ions an arrhenius base is a compound that produces hydroxide ions in water. Hcl(aq) + h2o(l) h3o+ (aq) + cl- (aq) hcl is an arrhenius acid. Nh3 (aq) + h2o(l) nh4 + (aq) + oh- (aq) nh3 is an arrhenius base. Arrhenius was the first scientist to quantify the effects of greenhouse gases (1896) from burning of fossil fuels, which stemmed from his hobby of studying the causes of ice ages. Arrhenius estimated that a doubling of co2 would cause a temperature rise of 5 - 6 c. He estimated that this would take about 3000 years and that it was a good thing as it would prevent another ice age. In a 1906 publication, arrhenius adjusted the value downwards to 1. 6 c.
