The subject of the research is Prussian blue, the synthesis of Prussian blue is present on many web pages, in various versions. What they have in common is the simplicity of execution. To the synthesis of the dye is added the search for iron in the blood, an analysis linked to the constitution of Prussian blue and the synthesis of a dye other than blue obtained using copper salts. But the novelty of the didactic proposal is the reproduction of some experiences made by Macquer in 1752 which for the first time deal with the composition of Prussian blue. Here are some parts of the memoir written by Macquer, Chemical examination of Prussian blue, from 1752, relating to the description of these experiences. In this way, laboratory activity is experienced as a reconstruction of the history of chemistry which had its fundamental pivot in laboratory activity.

PROF. ROBERTO POETI

Hi, my name is Roberto Poeti , a former teacher . I decided to create this blog to continue the dialogue on Chemical Scienze, its history and its teaching and to share the experiences of my trips I’ve done now and in the distant past.
“Even Chemistry is a beautiful journey into the knowledge of the matter“
