AbstractThe composition of nitric acid solutions is investigated by means Raman spectroscopy (RS). The results are compared to critically selected data from other authors. The value of the thermodynamic dissociation constant in an aqueous nitric acid solution at 25°C (Ka = $$\left[ {{H^ + }} \right]{\left[ {NO_3^ - } \right]_{\gamma '}}_ \pm ^2/\left[ {HN{O_3}} \right]{\gamma '_{HN{O_3}}}$$[H+][NO3−]γ′±2/[HNO3]γ′HNO3 = 35.5 ± 1.5M) is determined by analyzing an extensive set of reliable and…

Dissociation Constants of Hydrohalic Acids HCl, HBr, and HI in Aqueous Solutions
The acid dissociation constants (Ka) of HCl, HBr, and HI are determined using the equation $${{K}_{{\text{a}}}} = K_{{\text{a}}}^{'}f_{{{\text{HA}}}}^{\infty }$$, where $$K_{{\text{a}}}^{'}$$ is the…
Characterization of the ALSEP Process at Equilibrium: Speciation and Stoichiometry of the Extracted Complex
TLDR
The identity of the complexes extracted into the ALSEP process solvent from solutions of nitric acid is determined, and it is demonstrated that replacing one TEHDGA molecule with one (HEH[EHP])2 dimer is likely energetically favorable compared to Eu(TEHDGA)3·3NO3, whether the HEH,[EHP] dimers is monodentate or bidentate.
