ChemInform Abstract: ZUR EXISTENZ VON MANGANACETAT‐DIHYDRAT

Abstract

Die Existenz derTitelverbindung wird vorausgesagt und Bedingungen für seine Existenz im Gleichgewicht werden bestimmt.

Solubilities of manganese, cadmium, mercury and lead acetates in water fromT= 278.15 K toT= 340.15 K

“…As can be seen, the solubilities at T = 298.15 K coming from the Stoilova-Balarew (29) 298.15 1.6942 (27) 318.15 4.704 (29) group (14,17,22,24) are lower than expected. This results from an addition of about 2 per cent of acetic acid to suppress the possible hydrolysis of cadmium acetate.…”

“…At T = (273.15 and 293.15) K, they were determined by Molodkin and Linichenko (24) and at T = 298.15 K by Stoilova. (14,17,22) Solubilities of mercury acetate in water were reported at few temperatures, (4,6) but they are probably incorrect. There is a number of old investigations dealing with lead acetate solubilities, in 1914 performed by Jackson (26) and by Sandved (27) (1929) at T = 298.15 K; and in 1917 by Osaka and Hara (28) at T = (308.15 and 318.15) K. Systematic solubility measurements were performed by Dundon and Henderson (29) in 1922 in the temperature range T = 273.15 to T = 323.15 K by using float and gravimetric methods.…”

“…Manganese acetate solubilities at T = 298.15 K were measured by the StoilovaBalarew group, (14,16,22) Nikolaev et al (23) Tudorovskaya et al (25) and at T = 333.15 K by Balarew et al (18) In the context of formation of different hydrates in the solid phase, the solubility curve in (Mn(CH 3 CO 2 ) 2 + H 2 O) was determined by Balarew et al (8) in the temperature range T = 298.15 to T = 343.15 K. Known solubilities of cadmium acetate are very scarce. At T = (273.15 and 293.15) K, they were determined by Molodkin and Linichenko (24) and at T = 298.15 K by Stoilova.…”

“…The case of calcium acetate was investigated in 1887 by Krasnicki, (22) in 1902 by Lumsden, (23) and new solubilities were presented by Saury et al (24) at fixed temperatures. (10,12,16,20,25,26) Solubilities of barium acetate in water were determined in 1887 by Krasnicki, (22) and in 1903 by Walker and Fyffe, (27) and at constant a To whom correspondence should be addressed (E-mail: apelblat@bgumail.bgu.ac.il).…”
