A microcalorimetric determination of the thermodynamics of formation of the monoand bi-sulfato complexes of lanthanum in aqueous solutions between 25 and 55°C

  • Curran Simpson
  • Egon Matijević


Using a differential microcalorimeter, the formation constants and enthalpies of formation of the mono- and bi-sulfato complexes of lanthanum ion have been evaluated for aqueous acidic solutions over a temperature range of 25 to 55°C.
