Ions in an aqueous solutions display ion specific behavior that has been commonly exemplified by the Hofmeister series. Stemming from observations by Franz Hofmeister in the 1870s with egg white lysozyme, lyotropic effects led to a classification of ions on their abilities to salt in or salt out proteins. Because of the positive charge of lysozyme, the original series turned out to be different that th… pictures of marlette michiganWeb5 mar. 2012 · Mar 05, 2012, 01:25 ET.
