Cation-cation and anion-anion complexes stabilized by halogen bonds.
Stable minima showing halogen bonds between charged molecules with the same sign have been explored by means of theoretical calculations. The dissociation transition states and their corresponding barriers have also been characterized. In all cases, the results indicate that the complexes are thermodynamically unstable but kinetically stable with respect to the isolated monomers in gas phase. A...
متن کاملAnion and cation leaching or desorption from activated carbons from municipal sludge and poultry manure as affected by pH.
The conversion of municipal sludge and poultry manure to activated carbon results in a significant ash fraction that contains several different anions and cations. The objectives of this study were to determine whether the select ions are released or leached from virgin carbon into the sorption medium at different pH values. Activated carbon was placed in solutions of pH 1, 5, or 7, and the lea...
متن کاملAnion Absorption by Baker's Yeast.
Rates and equilibrium values of cation absorption by Baker's yeast, Saccharomyces cerevisiae, are in accord with a diffusion-limited exchange process which is independent of metabolic activity (7). At equilibrium the alkali ion content per unit volume of wet yeast exceeds the solution concentration by about 50fold in 10-3 M solution and about 800-fold at 10-5 M. Bromide anions in equilibrium wi...
متن کاملCation-Anion Balance during Potassium and Sodium Absorption by Barley Roots
Steady-state rates of potassium ion and sodium ion absorption by excised barley roots accompanied by various anions were compared with the rates of anion absorption and the concomitant H(+) and base release by the roots. The cation absorption rates were found to be independent of the identities, concentrations, and rates of absorption of the anions of the external solution, including bicarbonat...
متن کاملCluster structure of imidazolium salts in methanol controlled by the balance of interactions: cation-anion, cation-solvent, and anion-solvent.
We have studied the cluster structure of 1-butyl-3-methylimidazolium halide, bmimX (X = Cl, Br, I), in methanol solution by means of an electrospray mass spectrometer, which is specially designed for analysis of clusters isolated from solution. In positive ion mode experiments, the ratio of solvated bmim(+), bmim(+)(MeOH)(n) and ion-pair clusters, bmim(bmim(+)X(-))(m) was dependent on the count...
