The Standard Molar Enthalpies of Formation of Bazro3(S) and Srzro3(S)
The standard molar enthalpies of solution of BaZrO3(s) and SrZrO3(s) have been measured in (0.5 mol.dm-3 HF + 6.4 mol.dm-3 HNO3)(aq). From the results the standard molar enthalpies of formation of BaZrO3(s) and SrZrO3(s) have been calculated : -(1762.9+/-3.7) kJ.mol-1 and -(1763.5+/-3.3) kJ.mol-1, respectively.
