DENSITY AND ELECTRICAL CONDUCTANCE OF CALCIUM NITRATE TETRAHYDRATE PLUS ACETAMIDE MELT

Density and electrical conductance of the calcium nitrate tetrahydrate + acetamide melt were measured as functions of temperature and mole f i action of acetamide. On the basis of the additivity of molar volume, an alternative method has been suggested for estimating the densities of high- or low-melting anhydrous inorganic and organic salts using a suitable hydrate melt as solvent. Molar conductance data were analyze d by using the Vogel-Tammann-Fulcher equation. At ambient temperature the specific conductance of molten calcium nitrate tetrahydrate decrea ses by the addition of acetamide as was the case with the addition of KNOB.
