氢氧化钙的溶解度已经由许多工作人员以不同的精确度反复测定。首先发现的事实之一是，这种化合物的溶解度随着温度的升高而降低。在总结一些更精确数据的结果时，Mellor 1 [来自Dalton 2、菲利普斯、3、Wittstein 4和Bineau 5的综合结果]给出了氢氧化钙的溶解度，以每1000克水的氧化钙克数表示，在30 ℃时约为1.18。根据Lamy、Mobeu、Herzfeld和古特里的结果绘制的平均曲线，Seidell，6给出了该物质在25 ℃下的溶解度为1.16，以每1000克饱和溶液中的氧化钙克数表示。A. Lamv 7发现，氢氧化钙的不溶性根据其来源而变化。他给出了30 ℃时以每升溶液中氧化钙的克数表示的溶解度值。
The solubility of calcium hydroxide has been repeatedly determined by numerous workers with greatly varying degrees of precision. One of the first facts discovered was that the solubility of this compound decreases with rise in temperature. In summarizing the results of some of the more exact data, Mellor1 [from the composite results of Dalton2, Phillips, 3 Wittstein4 and Bineau5] gives the solubility of calcium hydroxide expressed in grams of cal-cium oxide per 1000 grams of water as approximately 1.18 at 30 degrees C. Seidell, 6 from the average curve obtained by plotting the results of Lamy, Mobeu, Herzfeld and Guthrie, gives a solubility for this substance of 1.16 expressed as grams calcium oxide per 1000 grms of saturated solution at 25 C. A. Lamv7 found that calcium hydroxide varies insolubility according to the source from which it is obtained. He gives the following values for thesolu-bility expressed as grams calcium oxide per liter of solution at 30 degreesC.
