The Solubility of Halides in Anhydrous Acetic Acid

Abstract

Solubility of Halides in Anhydrous Acetic Acid 2043 estimated, nevertheless, from the concentration of sodium iodate along the two curves, that the isothermally invariant point representing equilibrium between the two forms of the iodate must have the approximate composition 2.2% NaI03 and 45% NaC103. At higher concentrations of sodium chlorate the anhydrous sodium iodate has the lower solubility and is therefore the stable phase. These relationships are indicated in the table of results for this isotherm, but cannot be shown with any clearness in the figure. Summary Solubility measurements are given for the two ternary systems KI03-KC103-H20 and NaI03-NaC103-H20 at 25 and 50°. Neither compound formation nor solid solution is observed for either system at these temperatures. In the 50°i sotherm of the system NaI03-NaC103-H20, anhydrous sodium iodate is found to exist as a stable phase over a limited range of the solubility curve at high concentrations of sodium chlorate.

Study of Selective Layer for HCN Sensing

“…As the film is oxidized the acetate anion is entering the film at 0.51 V. In addition the curve (a) has poorly resolved cathodic band around 0.46 Vand anodic band with slightly developed maximum around 0.16 V. It is assumed that PANI · HgCl 2 in the presence of the acetate anion forms a double salt of the type PANI · HgCl 2 · 2CH 3 COOH. The formation of double salt of the type HgCl 2 · 2CH 3 COOH has been reported [30]. During the reduction of mercuric salts the mercurous ion, Hg 2þ 2 can readily form simultaneously HgO and Hg by the disproportionation reaction:…”

Anhydrous Acetic Acid as Nonaqueous Solvent

“…2 0 7 T h e reaction seems to be, *CH 3 COCH 3 + nl a + M(OAc) n -> MI n + nCH 3 GOGH 2 I + nHOAc (68) Pure anhydrous copper(II) chloride and bromide can be prepared by reacting the acetate either with the corresponding hydrogen halide or the acetyl halide. 2 0 7 T h e reaction seems to be, *CH 3 COCH 3 + nl a + M(OAc) n -> MI n + nCH 3 GOGH 2 I + nHOAc (68) Pure anhydrous copper(II) chloride and bromide can be prepared by reacting the acetate either with the corresponding hydrogen halide or the acetyl halide.…”

Tailoring Molecular Nanostructures of Gas sensitive Layers

“…HgCl2•2CH3COOH. [3] Using HgCl2 as the dopant for the PANI film, we reduced electrochemically the salt in acetic acid to the mercurous ion, Hg2 2+ . The formation of HgO and Hg by the disproportionation reaction: 2Hg2 2+ + 2H2O ↔ 2HgO + 2Hg + 4H + provides the binding sites in the PANI film that control the response to HCN gas.…”
