借助紫外-可见分光光度计测定Ca2+(aq)与FeO42-(aq)的平衡浓度,计算出ChFeO4在298.15K时的KSP0 常数和热力学函数△Hf0,△Gf0,S0分别为4.536 x 10-9,-1067.87kJ.mol-1,-923.17kJ.mol-1,-3.48J. mol-1.K-1.
The equilibrium concentration of Ca2 + (aq) and FeO42- (aq) was determined by ultraviolet-visible spectrophotometer. The KSP0 constant and the thermodynamic function △ Hf0, △ Gf0 and S0 of ChFeO4 at 298.15K were calculated to be 4.536 × 10 -9, -1067.87 kJ. mol-1, -923.17 kJ. mol-1, -3.48J. mol-1. K-1.
