Career

Fischer published about sixty works in German journals. He reported on the triple salt K3 Co6, also known as "Fischer's salt" and used it to separate nickel from cobalt. Fischer also observed the semipermeability of animal bladders in solutions, which he wrote about in "Über die Eigenschaft der thierischen Blase, Flüssigkeiten durch sich hindurch zu lassen." He also took great interest in electrochemical phenomena.
