The enthalpies of precipitation of silver halides and the enthalpies of solution of AgNO, KCl, and KBr in HO were measured in an adiabatic solution calorimeter. From the enthalpy measurements of KCl(c) and KBr(c) in AgNO(aq), and of AgNO(c) in KCl(aq), in KBr(aq), and in KI(aq), we calculated (in kJ · mol) -65.724, -84.826, and -111.124 for Δ° pptn(298.15 K) for the averages of the chloride, bromide, and iodide reactions, respectively. A reevaluation of the data for the enthalpy of solution of AgNO(c) has resulted in our selected best value, A table of enthalpies of dilution of AgNO(aq) is also given. The average standard entropy for the aqueous silver ion at 298.15 K is found to be .
在绝热溶液量热计中测量了卤化银沉淀的焓以及硝酸银、氯化钾和溴化钾在水中的溶解焓。通过测量氯化钾(c)和溴化钾(c)在硝酸银(aq)中的焓,以及硝酸银(c)在氯化钾(aq)、溴化钾(aq)和碘化钾(aq)中的焓,我们分别计算出氯化物、溴化物和碘化物反应的Δ° pptn(298.15 K)平均值(单位:kJ · mol)为-65.724、-84.826和-111.124。对硝酸银(c)溶解焓数据的重新评估得出了我们选定的最佳值,还给出了硝酸银(aq)稀释焓表。发现298.15 K时水合银离子的平均标准熵为 。
