Web1 jan. 2014 · There is an enormous amount of examples of specific ion effects, from thermodynamic and transport properties of aqueous electrolyte solutions to effects at the water-air interface, in biological systems (e.g., the nervous system and ion channels) and in colloidal interactions. WebIn alkali metal and lanthanide coordination chemistry, triphenylsiloxides seem to be unduly underappreciated ligands. This is as surprising as that such substituents play a crucial role, among others, in stabilizing rare oxidation states of lanthanide ions, taking a part of intramolecular and molecular interactions stabilizing metal-oxygen cores and many others. WebIt's not since it is nonpolar and can't form ion-ion, H-bonds, or dipole-dipole interactions with water. We can't get by by "breathing water" since not enough O 2 can be dissolved in water. That's why we have a protein in our blood called hemoglobin which specifically binds and carries O 2 , effectively increasing the "dissolved" concentration of oxygen by 100 fold. phone to mac bugs
