The Informational Reliability Evaluation of Zinc Nitrate Hexahydrate Physicochemical Properties for Applied Research

The authors propose an algorithm for determining the reliability of physicochemical properties using zinc nitrate hexahydrate as a case study. This compound is a promising phase change energy-saving material at low temperatures. The approach underscores the need to verify the informational reliability of a vast amount of experimental data. Dubious experimental values are averaged or excluded in determining the reliability of such properties as enthalpy, temperature of melting, density in the solid and liquid phases, heat capacity in the solid and liquid phases, and viscosity. Reliable literature properties are identified, and experimental measurements are made of the characteristics of zinc nitrate hexahydrate of various classifications to find correlations between reliable literature and experimental data.
