Standard enthalpy of formation of sodium paratungstate Na10H2W12O42 center dot 27H(2)O(s)
The standard enthalpy of decomposition of Na10H2W12O42. 27H(2)O(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. 27H(2)O(s) at 298.15 K was first obtained as -(21898.2+/-10.8) kJ mol(-1).
