补充资料：稀释热
| 稀释热 dilution，heat of 将一定量的纯溶剂加入到一定量的溶液中时产生的热效应。对于指定的溶质和溶剂，若稀释前溶液的量固定，则稀释热取决于温度、压力以及稀释前后溶液的浓度。稀释热分积分稀释热和微分稀释热。在定温定压下将一定量的纯溶剂加入溶液中，该过程中溶液浓度逐渐变小，产生的热效应称积分稀释热 ，用符号ΔdilH表示。设溶液的溶解热为ΔsalH（见溶解热），则(aΔsalH／ ¶nA)T，p，nB称微分稀释热，它是一定浓度下的稀释热。在工程中积分稀释热用得较多。ΔH可用量热计直接测量，也可由溶解热数据进行计算，计算公式为： ΔdilH＝ΔsolH2－ΔsolH1 式中ΔsolH1和ΔsolH分别为稀释前后两溶液的积分溶解热。而微分稀释热难以直接测量，可由测量结果绘制ΔsolH～nA曲线，则曲线上任一点的斜率即为该浓度下的微分稀释热。 |
