Abstract
Abstract
The thermal decomposition equilibria of ammonium europium chlorides (NH4)3EuCl6, (NH4)2EuCl5 and NH4Eu2Cl7 have been investigated by total pressure measurements in a membrane zero manometer. The thermodynamic data of these solid phases have been derived from the decomposition functions. The standard enthalpies of solution in 4n HCl (aq.) of (NH4)3EuCl6, (NH4)2EuCl5, NH4Eu2Cl7, EuCl3 and Eu2O3 were measured. On the basis of these values and tabulated data, the standard enthalpies at 298 K of the ammonium europium chlorides were derived and compared with the obtained results from the total pressure measurements.
