The Hofmeister series or lyotropic series is a classification of ions in order of their lyotrophic properties, which is the ability to salt out or salt in proteins. The effects of these changes were first worked out by Franz Hofmeister, who studied the effects of cations and anions on the solubility of proteins. Hofmeister discovered a series of salts that have consistent effects on the solu… Nettet21. mar. 2014 · Beyond Hofmeister.
