Abstract: Osmometric measurements prove that I in HI as well as I- form hydrates with 3 mols. H₂O, Br in CH₃CHBrCOOH, and Br^- with 2 mols. H₂O, and Cl in CH₂ClCOOH with 1 mol. H₂O. No hydration of Cl^- was detected. SO₄^2- and NO₃^- hydrate with 2 mols. H₂O, which indicates, according to the authors, the validity of the classical formulas O-.sbd.N .dbd.O N.dbd.O, S.dbd.O S.dbd.O S.sbd.O^- S.sbd.O^- contrary to the formulas proposed as consequence of the octet theory. Guanidine ion is formulated in view of osmometric measurements as a H ion co.ovrddot.ordinated with a mol. of guanidine: H₂N.sbd.C H₂N.sbd.C.dbd.N^2-H⁺N.sbd.H.
