This Day in Science History - January 7 - Eilhard Mitscherlich
January 7th is Eilhard Mitscherlich's birthday. Mitscherlich
was a German chemist who introduced the idea of isomorphism. He
theorized that chemical substances that crystallize together into a
solid will typically have similar chemical formulas. Isomorph compounds
can substitute each other when crystallizing and the shape of the
crystal will not change. Another property of isomorphic compounds
concerns the relative sizes and positions of the ions and cations of the
minerals. Isomorphic minerals will have the same coordination and
relative ion sizes of each component.
This property was later used by Jöns Jacob Berzelius in his attempt to create a table of elements based on atomic weights.
Mitscherlich was also the chemist who discovered permanganic and silenic acids and made several contributions to the understanding of arsenic, phosphorus and benzene derivatives. Find out what else occurred on this day in science history.
