An interlaboratory test for certification of potassium chloride as a certified reference material (CRM) for solution calorimetry

Solubility and dissolution enthalpy of xanthine

“…The overall accuracy of the calorimetric results was determined by comparing the precision of two calorimeters used independently for all measurements. For this purpose, the performance of these two calorimeters was tested by measuring the enthalpy of dissolution of ultra pure KCl, which was prepared and characterized as described by Günther et al (14) at T = 310.15 K. The value obtained, sol H m = (15.62 ± 0.18) kJ · mol −1 , is in good agreement with the calculated value sol H m = 15.82 kJ · mol −1 (based on data given in reference 15). This result verified that the performance of the calorimeters was reliable.…”

Thermochemical investigation of YBa2Cu3O7−δ superconductor doped by lutetium

“…To check the precision of the calorimeter, dissolution of a standard substance, potassium chloride, was performed. The obtained dissolution heat of KCl (17.529 ± 0.009 kJ/mol) is in a good agreement with the value recommended in the literature [20]. The experiments were performed at 298.15 K. The amount of substance used was about 0.1 g. (Y,Lu)123 pellets were stored in a dry box to prevent interaction with moisture or CO 2 .…”

Thermodynamic Properties and Stability of In‐Doped SrCeO3 Proton‐Conducting Ceramics

“…The program allows one to measure and [17] and 17.47 Ϯ 0.07 kJ mol -1 in ref. [18] A solution of 1 m HCl with 0.1 m KI was chosen as a solvent. A mixture of SrCl 2 , CeCl 3 , and InCl 3 was prepared in a ratio of 1:0.5:0.5.…”
