    Notes: Abstract Upper and lower bound estimates of the CuCl+ stability constants produced by various investigations have been quantitatively examined. Our analyses, including our own ultraviolet spectroscopic investigations, indicate that the CuCl+ stability constant in 1 molar HClO4 is β1=0.70±0.23. The CuCl+ molar absorptivity at a wavelength of 250 nm was determined as 1860 cm2-mol−1. Our analyses suggest the bound β 1 ′≤0.37 for the formation constant of MgCl+ at one molar ionic strength.

    Lead chloride complexation using ultraviolet molar absorptivity characteristics (1981)
    Springer
    Journal of solution chemistry 10 (1981), S. 243-251 
    Details
    ISSN: 1572-8927

    Notes: Abstract The molar absorptivities of Pb2+, PbCl+, PbCl2, and PbCl 3 − were obtained between 210 and 300 nm. Molar absorptivity data were used to determine lead speciation directly from Pb(II) absorbance characteristics in a variety of media including natural seawater. The absorbance characteristics of lead in a particular chloride medium reveal the lead chloride formation constants appropriate to that medium. Our analyses indicate that lead chloride formation constants are significantly smaller in MgCl2 media than in HCl at constant ionic strength.
