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
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.
Behaviors of ALSEP Organic Extractants: an Atomic Perspective Derived from Molecular Dynamics Simulation
ABSTRACT Molecular dynamics simulations were performed on mixtures of N,N,N′,N′-tetra(2-ethylhexyl)diglycolamide (T2EHDGA) and 2-ethylhexylphosphonic acid mono(2-ethylhexyl) ester (HEHEHP)
Thermodynamic Modeling of Nitric Acid Speciation Using eUNIQUAC Activity Coefficient Model
