“…Activity coefficients determined in this work by gasliquid chromatography (GLC) were found to agree well in the cases where comparison with those extrapolated from static measurements in the bulk liquid at well-defined equilibrium conditions were available (2,7,14). Other workers have found the same result for other systems (4, 8, ).…”

Dame, for computer results. Research assistantships from the Atomic Energy Commission and the National Aeronautics and Space Administration are gratefully acknowledged by W. A. J. :, = ,+ 1.515 (µ)1'2 1 + 1.6 (µ)1'2 RESULTS AND DISCUSSIONThe calculated values of the ionization constants are listed in Table I. The precision f the pKa values is the standard deviation of five sets of two data points for each titration. In the case of the solutions in which KC1 was added, the constants are concentrationand ionic strengthdependent, and are not thermodynamic values. Since the Debye-Hiickel law does not hold in solutions of high ionic strength, no corrections were attempted.The results of the titration at 28.2°C. in which no KC1was added (Ka = 5.90 x 10~2 and Ka = 2.93 x 1CT3) are similar to those reported by Charton (5) at 25°C. (7.07 X 10-2 and 3.55 x 10 3). Apparently, the early work of Ashton and Partington was not accurate.

“…1-Nitroso-2-naphthol was synthesized according to the procedure described by Vogel (29). The purification procedure was basically that reported by Ilinski (14) and was repeated four times before combustion. The resulting pure material had a melting point range of 106.6°to 107.0°C.…”

“…According to Boyland (4) the red cobalt 2-nitroso-l-naphtholate complex is produced rapidly at room temperature over the pH range 4 to 9. In slightly acidic solutions excess reagent is precipitated (4), and iron interference is reported (8). Therefore, color development was effected in alkaline media.…”

“…Cobalt forms precipitates with several o-nitrosophenol derivatives, including 2-nitroso-l-naphthol. This compound, formerly named ß-nitroso-a-naphthol, was reported by Ilinski (8) to give reddish brown cobalt precipitates. Yoe and Barton (11) described quantitative colorimetric studies with this reagent.…”
