What did Stanislao Cannizzaro contribute at the First International Congress of Chemists held in 1860?
What did Stanislao Cannizzaro contribute at the First International Congress of Chemists held in 1860?
He championed Amedeo Avogadro’s notion that equal volumes of gas at the same pressure and temperature held equal numbers of molecules or atoms, and the notion that equal volumes of gas could be used to calculate atomic weights. In doing so, Cannizzaro provided a new understanding of chemistry.
What is Stanislao Cannizzaro most famous for?
Stanislao Cannizzaro, an Italian chemist, was born July 13, 1826. Cannizzaro was a very accomplished organic chemist, but he is best known for a single paper he published in 1858. Amedeo Avogadro had proposed, almost 50 years earlier, that the basic chemical unit is the molecule, not the atom.
What contribution did Stanislao Cannizzaro make to science?
Through his important contributions to the theory of atomic weights, Cannizzaro guided his fellow chemists through a crucial time. In the mid-19th century European chemists were in a state of confusion and disagreement over the most fundamental concepts of chemistry.
What did Cannizzaro published in 1858?
A single system of atomic formulas In his 1858 pamphlet, Cannizzaro showed that a complete return to the ideas of Avogadro could be used to construct a consistent and robust theoretical structure that fit nearly all of the available empirical evidence.

By all accounts Cannizzaro was much clearer in his explanations than Avogadro, and as an organic chemist he also showed how Avogadro’s ideas could be applied to this branch of chemistry.
Where did Stanislao Cannizzaro get his idea for the periodic table?
Mendeleev acknowledged that his periodic table was inspired by Cannizzaro’s work. Stanislao Cannizzaro. Born in Palermo, Sicily, where his father was a magistrate and the minister of police, Cannizzaro later attended medical school there, which kindled his interest in chemistry.
