LI.—The quaternary system lead acetate–lead chloride–acetic acid–water at 25°

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

“…Lead acetate solubilities (23,(26)(27)(28)(29) agree very well with our results (figure 4). This acetate is very soluble in water, especially at higher temperatures (T > 320 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.…”

“…The extraordinarily high solubility of lead acetate in water, in acetic acid and with alkali acetates is discussed by Sandved. (27,32) The authors appreciate the excellent technical assistance of Miss Abu Bal'el Nazamia.…”

“…(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. Recently, Nikolaev et al (23) …”
