Apparent molar volumes and apparent molar heat capacities of aqueous magnesium nitrate, strontium nitrate, and manganese nitrate at temperatures from 278.15K to 393.15K and at the pressure 0.35MPa

“…15 6 T/K 6 368. 15) and at p = 0.35 MPa using a vibrating-tube densimeter (model DMA 512, Anton PAAR, Austria).…”

“…15 6 T/K 6 368. 15) and at p = 0.35 MPa using a vibrating-tube densimeter (model DMA 512, Anton PAAR, Austria). We then calculated V / (m, T) by equation (1) as described previously [1,2]:…”

“…A twin fixed-cell, power-compensation, differential-output, temperature-scanning calorimeter (NanoDSC 6100, Calorimetric Sciences Corp., Lindon, UT, USA) was used to measure massic heat capacities c p,s of the aqueous Mg(NO 3 ) 2 , Sr(NO 3 ) 2 , and Mn(NO 3 ) 2 solutions at (278. 15 6 T/K 6 393.15) as described by Niederhauser and Woolley [1].…”

“…Values of V / were determined at (278.15 6 T/K 6 368. 15), and values of C p,/ were determined at (278.15 6 T/K 6 393. 15).…”

“…15), and values of C p,/ were determined at (278.15 6 T/K 6 393. 15). Equations in m and T were fitted by regression to our results, and values of standard partial molar volumes V 2 and standard partial molar heat capacities C p;2 were obtained over the ranges of T investigated.…”
