  • New determination of mercurous salts by volumetric precipitation
    作者:F. Burriel-Marti、F. Lucena-Conde
    DOI:10.1016/0003-2670(50)80055-7
    日期:1950.2
    proposed for the titration of mercurous salts, similar to that of volhard. As a reagent a solution of potassium mercurithiocyanate, which precipitates the mercurous ions, in compounds such as Hg2(SCN)2,is used; a solution of ferric sulphate is used as an indicator. The mercurous and mercuric ions can be determined in a mixture by effecting two titrations, one direct and the other after oxidation, with permanganate
    在讨论了 Hg2(SCN)2 的歧化条件后,提出了一种类似于 volhard 滴定汞盐的方法。作为试剂,使用硫氰酸汞钾溶液,它可以沉淀汞离子,在 Hg2(SCN)2 等化合物中;硫酸铁溶液用作指示剂。用高锰酸盐进行两次滴定,一次直接滴定,另一次氧化后滴定,可以测定混合物中的亚汞和汞离子。
  • Direct titration of mercury (i) with potassium permanganate

    Abstract Mercurous solutions can bc successfully titrated with potassium permanganate in presence of 0.5–1 N H 2 SO 4 and 1–1.5% NaF at 35–50°C, Sharp end-points arc obtained when the maximum concentration of monovalent mercury after mixing with the other reagents is 0.005 N . At higher concentrations the reaction is sluggish and, the end-points arc not sharp.

  • Reduction of the Aqueous Mercuric Ion by Sulfite:  UV Spectrum of HgSO<sub>3</sub> and Its Intramolecular Redox Reaction
    作者:Lisa Van Loon、Elizabeth Mader、Susannah L. Scott
    DOI:10.1021/jp994268s
    日期:2000.3.1
    Aqueous hydrogen sulfite reacts with Hg2+ to form, in the absence of excess HSO3-, the HgSO3 complex, observed here for the first time. Its UV spectrum is described by e(234 nm) = (1.57 ± 0.05) × 104 M-1 cm-1. HgSO3 decomposes in an intramolecular redox reaction which is kinetically first-order. The rate constant is independent of [Hg2+], [HSO3-], [O2(aq)], and ionic strength. An acid-assisted pathway
    在没有过量 HSO3- 的情况下,亚硫酸氢水溶液与 Hg2+ 反应形成 HgSO3 络合物,这是首次在此观察到。其紫外光谱由 e(234 nm) = (1.57 ± 0.05) × 104 M-1 cm-1 描述。HgSO3 在分子内氧化还原反应中分解,这是动力学一级的。速率常数与 [Hg2+]、[HSO3-]、[O2(aq)] 和离子强度无关。由于 HgSO3H+ 的贡献,酸辅助途径在 pH ≤ 1 时变得显着。HgSO3 的分子内反应速率是通过将 Hg0 产物捕获为 Hg22+ 来测量的;速率常数的值为 k0 = (0.0106 ± 0.0009) s-1,温度为 25.0 °C,pH 3。pH 3、ΔH‡ 和 ΔS‡ 的活化参数为 (105 ± 2) kJ/mol 和 (68 ± 6) J/mol·K,分别与单分子键断裂机制一致。
  • THE SIGNIFICANCE OF THE "MERCURINIUM ION" IN OXYMERCURATION
    作者:A. G. Brook、George F Wright
    DOI:10.1139/v51-036
    日期:1951.4.1

    The complex formed by mercuric nitrate with cyclohexene seems not to resemble similar argentous, cuprous, and platinous salt complexes, since it is stabilized by nitric acid while they are decomposed by acidic media. Furthermore, the cyclohexene – mercuric nitrate – nitric acid system is not stable as are the others in absence of air but decomposes to yield two equivalents of mercurous salt and one equivalent of formylcyclopentane. One or both of these products are presumed to be the material which earlier workers by implication defined as 1-hydroxy-2-nitratomercuricylohexane. It has now been found that this product could not have been formed under the reaction conditions used by these earlier workers. Finally the solubilization of cyclohexene in aqueous mercuric nitrate, on which the earlier workers based their concept of an alkene-mercurinium ion, does not have its counterpart in the solubilization of cyclohexene in aqueous mercuric acetate, since the rate of solution in the latter case is not faster than the rate of hydroxymercuration. In consequence there is no present evidence that such an ion is involved in oxymercuration of alkenes.

    用汞硝酸形成的环己烯络合物似乎与类似的银、铜和铂盐络合物复合物不同,因为它受到硝酸的稳定,而它们在酸性介质中会分解。此外,环己烯 - 汞硝酸 - 硝酸体系在没有空气的情况下不稳定,而会分解产生两当量的亚汞盐和一个当量的甲基环戊烷。这两种产物中的一种或两种被认为是早期研究人员通过暗示定义为1-羟基-2-硝基汞环己烷的材料。现在已经发现,在这些早期研究人员使用的反应条件下,这种产物不可能形成。最后,在水合汞硝酸中环己烯的溶解,这是早期研究人员基于烯烃-汞离子概念的基础,与环己烯在水合乙酸汞中的溶解没有对应,因为在后一种情况下的溶解速度不会快于氢氧汞化反应速度。因此,目前没有证据表明这种离子参与烯烃的氧汞化过程。
  • Study of Polarographic Anodic Wave in the Presence of Chloride Ions by a New Numerical Method
    作者:Kenji Kikuchi、Teisuke Murayama
    DOI:10.1246/bcsj.61.3159
    日期:1988.9
    A new numerical method is applied to the simultaneous diffusion equations describing the anodic process of mercury in solutions in the presence of chloride ions. The terms corresponding to precipitation and dissolution of mercury(I) chloride are included in the differential equations. It is found that the differential equation for precipitate particles should be rewritten using the backward space difference
