The Heat of Oxidation of Arsenious Oxide to Arsenic Oxide in Aqueous Solution.

Correlation and prediction of thermodynamic properties of nonelectrolytes at infinite dilution in water over very wide temperature and pressure ranges (2000K and 10GPa)

“…The analysis of data makes possible to allocate hydroxides of metalloids as a specific class of compounds (representatives of this class are B(OH) 3 , Si(OH) 4 , As(OH) 3 , Sb(OH) 3 , Ge(OH) 4 , etc). Precise V 1 2 data are measured for B(OH) 3 (Ellis and McFadden, 1972;Ward and Millero, 1974;Hnědkovský et al, 1995;Ganopolsky et al, 1996;Abdulagatov and Azizov, 2004) and for As(OH) 3 (Anderson and Story, 1923;Bjellerup et al, 1957;Perfetti et al, 2008). For Si(OH) 4 the partial molar volumes were estimated from the equation (Manning, 1994) describing solubility of quartz in water.…”

Standard enthalpies of combustion of five halogen-substituted 8-hydroxyquinolines by rotating-bomb calorimetry

“…The energy of oxidation of As 2 O 3 (aq) to As 2 O 5 (aq) was taken from the work of Bjellerup (12) and corrections were applied to account for As 2 O 5 oxidation. (13) In the combustion of organic iodine compounds, only elemental iodine is found in the combustion products.…”

Densities and heat capacities of aqueous arsenious and arsenic acid solutions to 350°C and 300bar, and revised thermodynamic properties of , and iron sulfarsenide minerals

“…The infinite-dilution heat-capacity values for both arsenic species at the reference conditions of 298 K, 0.1 MPa, C p (As(OH) 3 ) = 85 ± 10 J/(mol K), C p (AsO(OH) 3 ) = 105 ± 10 J/(mol K), were obtained by linear extrapolation of the moderate-temperature data measured in this study at 324 and 348 K versus absolute temperature. Our value for As(OH) 3 may be compared to that reported by Bjellerup et al (1957) from limited heat-capacity measurements on 0.1 m arsenious acid solutions, C p $ 98 J/(mol K). No other experimental data could be found in the literature.…”
