The molar enthalpies of solution of CaTeO3, CaTe2O5, TeO2, and CaCO3 in HCl(aq, ) have been measured by using an isoperibol calorimeter. From these results and other auxiliary data, the standard molar enthalpies of formation DfH°m(298.15 K) of CaTeO3(s) and CaTe2O5(s) have been calculated to be -(98
