本刊1957年第12期“醇溶液的配制”一文,已详细讨论了配制乙醇溶液时温度和体积变化的影响,同时还介绍了标准温度为15.5℃的“醇稀释表”和以15.6℃为标准的“醇浓度校正表”。但近年出版的一些书刊在介绍乙醇溶液的稀释方法时,仍将普通溶液的计算公式简单地用于乙醇溶液,没有考虑温度和体积变化的影响。如按这些方法稀释,将不能配得准确浓
This article published in 1957 the twelfth “” alcohol solution “article, has discussed in detail the preparation of ethanol solution temperature and volume changes, but also introduced the standard temperature of 15.5 ℃ ” alcohol dilution table “and 15.6 ℃ as the standard ”alcohol concentration calibration table ". However, some books published in recent years introduce the dilution method of ethanol solution and simply use the formula of common solution in ethanol solution without considering the influence of temperature and volume change. If diluted according to these methods, will not be able to get the exact concentration
