“…DMSO was used without further purification. The density values of (1095.196 ± 0.009) kg·m −3 at 298.15 K for DMSO and (786.458 ± 0.006) kg·m −3 for methanol were found in the present study, while literature values vary from 1095.271 kg·m −3 to 1097.2 kg·m −3 for DMSO and from 786.36 kg·m −3 to 786.64 kg·m −3 for methanol. − …”

“…The density values of (1095.196 ( 0.009) kg • m -3 at 298.15 K for DMSO and (786.458 ( 0.006) kg • m -3 for methanol were found in the present study, while literature values vary from 1095.271 kg • m -3 to 1097.2 kg • m -3 for DMSO and from 786.36 kg • m -3 to 786.64 kg • m -3 for methanol. [11][12][13][14][15][16][17][18] Sound velocity in pure methanol was found to be between (1101.14 and 1101.34) m • s -1 . The range compares reasonably well with values of 1098.64 m • s -1 and 1101.9 m • s -1 published by Lankford and Resa and the value obtained by our laboratory in previous studies.…”

The temperature dependence of the density of divalent transition metal perchlorates in dimethylsulfoxide as well as cobalt(II), nickel(II) perchlorates, and copper(II) trifluoromethanesulfonate in methanol was determined. Moreover, sound velocities for solutions of cobalt(II), nickel(II) perchlorates, and copper(II) trifluoromethanesulfonate in methanol have been measured at 298.15 K. From these data, the partial molar volumes, partial molar expansibilities, and partial molar isentropic compressibilities have been estimated. The results obtained are discussed in terms of ion-solvent interactions.

“…For NaBPh 4 , the literature value [6] of the standard partial molar volume is rather uncertain because the estimation of the V 0 / (NaBPh 4 ) has been based on an insufficiently small number of the solutions (only three solutions at different concentrations of the electrolyte have been used). In the case of NaBr, NaBPh 4 , and Ph 4 PBr, an extended examination [10] related to temperatures (293.15, 298.15, and 313.15) K has been made. The reported values are somewhat higher than that from this study, but the agreement is still reasonable.…”
