Abstract :
The standard enthalpy of decomposition of Na10H2W12O42·27H2O(s) at 298.15 K was measured using the method of three-step calorimetry in a Calvet twin-vessel microcalorimeter. The standard enthalpy of formation of Na10H2W12O42·27H2O(s) at 298.15 K was first obtained as −(21898.2±10.8) kJ mol−1.
