Abstract
The differential enthalpies of solution of sodium nitrate in water have been measured calorimetrically at 25°C, from 0.5 to 10.4 mol (kg H2O)−1. The concentration dependence is described by the equation ΔH=20.4537+1.0562m1/2-7.0568m+2.8659m3/2-0.3382m2 From the calorimetric measurements, the enthalpy of crystallization of sodium nitrate was calculated as ΔHc=9.98±0.16 kL-mol-1. The literature data on the solubility, activity and osmotic coefficients of NaNO3 at 25°C yielded a value of −9.98±0.38 kJ-mol−1. The good agreement between the experimental and calculated ΔHc values indicate the reliability of the input data.
