摘要
提出了一个估算正负离子标准水合焓ΔhHmθ(Mn±)的简易公式。ΔhHmθ(Mn±)的计算值与报道值相对误差在8%以内。用所建立的计算式预估了一些已知ΔhHmθ(Mn±)和ΔfHmθ(Mn±,aq,∞)或ΔfHmθ(Mn±,g)值的气态正负离子的标准生成焓ΔfHmθ(Mn±,g)和正负水合离子的标准生成焓ΔfHθm(Mn±,aq,∞)。
A simple formula of estimating the standard hydrous enthalpy of cation and anion,△hHm^θ(M^n*) was presented. The errors between calculated and reported values of △hHm^θ(M^n*) was within 8%. The standard enthalpies of formation of cations and anions with known △hHm^θ(M^n*) and △fHm^θ(M^n*,aq,∞) or △fHm^θ(M^n* ,g), △fHm^θ(M^n* ,g) or △fHm^θ(M^n* ,aq,∞) were estimated by the formula established.
