Abstract:

The standard enthalpy of formation (ΔfHm,298KΘ=-2510.73kJ•mol-1) of a new double salt K2Mg(IO3)4•2H2O was determined by calorimetry. The standard free energy (ΔfGm,298KΘ=-2061.9kJ•mol-1) and standard entropy (Sm,298KΘ=258.27J•K-1•mol-1) were calculated.

Key words: Double salt, Iodates, Calorimetry, Thermodynamic properties
