Surface tension of some molten salt hydrates by the pendant drop technique

Surface tension of some molten salt hydrates by the pendant drop technique. Sada, Eizo; Katoh, Shigeo; Damle, Hari G. (Dep. Chem.In this study， 10196-18-6 and 10025-77-1 are also used. Eng., Kyoto Univ., Kyoto 606, Japan). J. Chem. Eng. Data, 29(2), 117-19 (English) 1984. CODEN: JCEAAX. ISSN: 0021-9568. DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) Section cross-reference(s): 68 Surface tensions of molten salt hydrates such as Cd(NO3)2.4H2O, Ca(NO3)2.4H2O, Cr(NO3)3.9H2O, Mn(NO3)2.6H2O, Ni(NO3)2.6H2O, Zn(NO3)2.6H2O, and FeCl3.6H2O were measured by using the pendant drop technique. The exptl. values agree with those detd. by previous workers, obtained by using the differential capillary rise method. With the pendant drop method, it was possible to obtain some new data at low temps. in the supercooled region where the molten salt hydrates become highly viscous and the other methods are likely to fail to yield accurate results. In the case of the nitrate hydrate melts, the main contribution to the surface tension of the liq. seems to be due to the salt rather than the coordinated water, while in the case of FeCl3.6H2O, the surface of the melt seems to be predominantly occupied by the coordinated water. .
