- 中文摘要: Thermometric titrations of lanthanum perchlorate, titanium (III)-chloride, uranium (IV)-sulfate, and uranyl sulfate with EDTA solutions were carried out by using a Keithley nanovoltmether with a rhodium-platinum thermocouple at 25°±0.01°. the formation of LaY¯, TiY¯, U(IV)Y and UO2HY¯ ions was confirmed. The heat of reaction for the system, Ti(III)+H2Y2¯=TiY¯+2H+, Was given by ⊿H1=1.933-1.422×10..√m +2.056×10.. (in cal) and the limiting value was evaluated to be ⊿H1°=1.9 kcal mol¯1 at 25℃.
