Abstract

The enthalpy of solution in 1.000 mol/dm3 hydrochloric acid of californium tribromide in its room temperature stable monoclinic form was measured at 298.15 +/- 0.05 K and at p(o)=101.325 kPa as -(181.4 +/- 0.9) kJ/mol. This result is combined with the previously determined enthalpy of solution of californium metal in the same medium at comparable concentrations. The value obtained is compared with previously estimated values for this compound and, together with the experimental values for the molar enthalpies of formation of uranium, neptunium and plutonium tribromides, is used to estimate the molar enthalpies of formation of americium, curium and berkelium tribromides.
