Ionization values

Since hypohalous acid is a much more active disinfectant than the hypohalite ion, the effect of pH on ionization becomes important. Hypobromous acid has a lower ionization value than hypochlorous acid and this contributes to the higher disinfectant activity of BrCl compared with chlorine. 

Make a tabulation for each acid of the number of grams of the four components present in 1 liter of 0.1 N solution (1) water, (2) un-ionized acid, (3) hydrogen ion, (4) acid radical ion. (Consult table of ionization values on page 100.) Arrange the tabulation for each acid somewhat on the following plan. 

Since we may see in the table of ionization values that pure water contains but 0.000,000,1 mole of H+ ions and 0.000,000,1 mole of OH- ions per liter, we may know in advance that when an acid and a base are mixed the H+ and OH- ions cannot remain in the presence of each other, but must unite according to the reaction...

In electron bound complexes of C60 with aromatic hydrocarbons, the intensity of the aromatic hydrocarbon anion from collisional ionization is larger than that for the aromatic hydrocarbon. However, it is known that the adiabatic electron affinities of the aromatic hydrocarbons are significantly lower than that of C60. In these cases the relative intensities were attributed to a localized anion. When the benzanthracene and phenanthrene electron bound dimer is dissociated, the intensity of the phe-nanthrene anion is only about one-half that of the benzanthracene anion, while the electron affinity of benzanthracene is 0.72 eV and that for phenanthrene is 0.30 eV. The experimental data cannot be disputed. The ion ratio gives a AEa of 0.08 eV or the Ea of benzanthracene = 0.30 + 0.08 = 0.38(10) eV. Therefore, some other explanation must be presented. In the case of C60 excited anion states are observed and three degenerate LUMO + 1 are calculated with positive electron affinities. Benzanthracene has an excited-state MO at 0.38 eV that gives an Ea of 0.38 eV. Just as C60 has multiple LUMOs, so also does benzanthracene. Because the collisional ionization values are the most recent, they are returned by a search of the NIST tables for CH molecules. These values are fisted in Chapter 10 [61-63]. 

Fig. 7. Different estimation of the mean charge state of ions in carbon foils. The lines indicated ND and SG show the empirical fitting expressions for the average charge state of ions crossing solid foils given by Nikolaev-Dmitriev [55] and Schiwietz-Grande [56], respectively. The line BK is the Brandt-Kitagawa model [15] for the equilibrium charge of ions moving inside solids. The line ZBL is the equilibrium ionization value proposed by Ziegler et al. [9].

Discussion of Actinide Ionization Potentials. The ionization potentials of actinides determined by laser techniques are given in Table IV together with values determined by surface ionization, appearance potential and semi-emperical methods. For uranium, all values are low compared with the values determined by laser techniques with the exception of the surface ionization value by Smith and Hertel.(z ) The spectroscopic values by Sugar jL were obtained from the 5f 7s - 5f 7s8s intervals interpolated from intervals known for the higher actinides. Except for Sugar s value, all the neptunium ionization potential values are low relative to the more accurate values determined by laser methods. The Rydberg series values are the preferred ionization potentials. 

A more detailed analysis of Pontallier s experiment (1981) makes it possible to distinguish between the free anthocyanin concentration (Al) and that of anthocyanins combined with tannins (T-A) (Section 6.4.2). Multiplying each of these values by the ionization value (Section 6.4.5) indicates the proportion of each type of molecule in colored form. The difference represents the...
