我们一般所碰到的化学反应,大部分都是在溶液里进行的。因此,一个物质在某一溶剂中是否能溶解和溶度有多少,就成为非常重要的问题。譬如,实验室中某人发生了汞盐中毒,我们就得赶紧灌以生蛋白或牛乳,使溶在胃液中的汞盐沉淀(亦即减低汞盐的溶度),然后把它从胃中洗出,这样可以挽救中毒者的生命。在有机定性分析中,我们利用样品在各种溶刺中溶度的不同来决定它是属于那一类化合物。而在无机分析化学中,各种离子的分离,也是利用它们在不同情况下溶度的变化。可惜现在对于溶度的同题,理论上还没有得到很好的
Most of the chemical reactions we commonly encounter are in solution. Therefore, it is a very important issue whether or not a substance can be dissolved and dissolved in a certain solvent. For example, in a laboratory where mercury poisoning occurs, we have to quickly irrigate the raw protein or milk to precipitate the mercury salt dissolved in the gastric juice (that is, to reduce the solubility of the mercury salt) and then remove it from the stomach Wash out, this can save the life of poisoning. In qualitative qualitative analysis, we take advantage of the solubility of the sample in various solutes to determine which compound it belongs to. In inorganic analytical chemistry, the separation of various ions, but also the use of their solubility in different circumstances change. Unfortunately for the same problem of solubility, in theory, have not been very good
