Abstract

We have employed titration calorimetry to investigate the aqueous solution chemistry of the Th(IV) + oxalate coordination system. The enthalpies of formation of the two oxalic acid species and the first Th-oxalate complex have been measured at an ionic strength I=1.0M and temperature t=25°C. Corresponding entropy values were calculated from the van't Hoff equation, and a thermodynamic summary of the Th/H/oxalate system is presented in a table.
