SS Connection

My Chemistry PBL is about reversible reactions. For my SS Connection, I will be explaining the prevalence of reversible reactions throughout science. I will explain the history, important findings, and the people behind reversible reactions. On this page, I will post my SS connection portraying how reversible reactions were discovered, and how they influenced science.

Reversible reactions were crucial in science throughout history, because they helped scientists figure out why certain things were happening during their experiments when they thought that reactions always proceeded in one direction. The concept behind reversible reactions was first introduced by Claude Berthollet, a French chemist, in 1803, after discovering the growth of sodium carbonate crystals at the edge of a lake in Egypt. He determined that this was the reverse of a common reaction, which could have been caused by the extra salt in the lake that helped stimulate the reverse reaction. To substantiate Berthollet's discovery, Waage and Guldberg created a law of mass action in 1864. The Le Chatelier's principle was created by Braun and Le Chatelier, and this said that there were more factors (other than just concentration) that could contribute to achieving equilibrium in a reaction. Because of these discoveries and introductions, scientists all over the world were able to understand and discover more clearly how and why chemical reactions occurred the way they did.
