Working on the work “Fundamentals of Chemistry”, he discovered one of the fundamental laws of nature – the Periodic Law of Chemical Elements. Predicted the existence, calculated the atomic masses and described the properties of 11 more elements – gallium, scandium, germanium and others.
Opened the theory of absolute boiling point of liquids. Designed pycnometer; a device for determining the density of a liquid. Created a hydrated theory of solutions. Found the general equation of state of an ideal gas. He put forward a hypothesis of the origin of oil from carbides of heavy metals.
WORKS “Organic Chemistry” (1861), “Fundamentals of Chemistry” (1869-1871), more than 500 works.
