Ca(NO3)2−H2O system Solubility of the Ca(NO3)2−H2O system have been reported
11
in previous literatures. Bassett and Taylor1 detected the solubility of Ca(NO3)2
12
solution at the temperature range from 244.45 K to 424.15 K. Toylor and Henderson2
13
investigated the system from 273.15 K to 315.85 K again, and gave solubility of the
14
unstable Ca(NO3)2·4H2O. Ewing et al3 detected the temperature-composition diagram
15
of the system from 257.05 K to 324.75 K by using the freezing point method, and
16
found a metastable region at temperature range from 293.15 K to 324.1 K. In this
17
work, we detected the solubility of the system at T = (273.15, 298.15, and 323.15) K.
18
All above solubility data but metastable data are shown in Figure 1, the line in Figure
19
1 is calculated values using parameters of table 5 and 6 in this work. The relative
20
deviation between our experimental data and the data from Bassett and Taylor1 at
21
273.15 K, 298.15 K, and 323.15 K are 0.02, 0.0089, and 0.01, respectively. Average
22
absolute relative deviation (AARD, AARD  1/ N  ( wexp  wcal ) / wexp ) between
N
i 1
23
calculated values and the reference data from above every source is less than 0.0085.

LiNO3-H2O system Many researchers have reported solubility data of the
6
LiNO3-H2O system since 1903.4-11 Donnan and Burt4 gave the solubility data from
7
273.25 K to 344.05 K. Campbell and Bailey5 detected the solubility in a temperature
8
range from 255.45 K to 348.75 K. Zeng et al6 gave a detailed study of solubility of the
9
system from 273.15 K to 342.55 K. Luo et al7 measured some thermophysical
10
properties of LiNO3 solution containing solubility in range of temperature from
11
277.15 K to 431.15 K. Mesones et al8 measured the solubility of the system in the
12
temperature range from 278.6 K to 339.7 K using a new device. In this work, we just
13
detected the solubility of LiNO3−H2O system at T = (273.15, 298.15, and 323.15) K.
14
All these experimental data are plotted in Figure 2. The solubility data from Zeng,6
15
Campbell5, Luo7 and our data are consistent with each other very well, and slight
16
different from some data of Donna4 and Mesones8, which are somewhat scattered and
17
higher than results of the formers5-7. The relative deviation between our data in this
18
work and above reference data at 273.15 K, 298.15 K and 323.15 K are all less than
19
0.012. The line in Figure 2 is calculated value using parameters of table 5 and 6 in this
20
work, AARD between calculated values and the data from Campbell5, Zeng,6 and
21
Luo7 are all less than 0.0073, and the AARD between calculated values and the data
22
from Donna4 and Mesones8 are 0.021 and 0.034, respectively.
