Enthalpy changes for the reaction of HCl(aq) with Na 2 WO 4 (aq) were measured at T = 298.15 K in a HT-1000 calorimeter. The standard enthalpy of reaction for the formation of W 7 O 6- 24 (aq) was calculated on the basis of the experimental results, r H o m (298.15 K) = -(320.7 ยฑ 1.0) kJ โ€ข mol -1 .
