氯化钠制备
Ca 2+ Mg 2+Fe 3+等杂质离子。检验这些离子合格后，过滤，在搅拌下向滤液中加入化学纯盐酸进行中和至ph=4～5。加热蒸发使晶体全部析出。离心甩干，置于烘箱内于80～100℃烘干，得试剂氯化钠。
5.加热搅拌使40g分析纯氯化钠溶解于120ml高纯水。加入2～3ml铁溶液 （7mg／ml ） ，搅拌均匀后，滴加提纯氨水至ph值为10左右。水浴加热使氢氧化铁沉淀析出，过滤。滤液放在铂皿中，低温密闭蒸发至结晶薄膜，冷却抽滤，乙醇洗涤后，在真空干燥箱内于105℃和2666Pa压力下干燥。此法得到的氯化钠经光谱定性分析仅含微量Si、AL、Mg和痕量Ca。 6. 盐田法 这是古老的制盐方法，海水受热，水分逐渐蒸发，盐的浓度逐渐升高，可以得到各种盐。当水分蒸发到90%时，食盐开始析出。 7. 电渗析法 利用电力使海水中的氯化钠浓缩。该方法是日本主要的氯化钠生产方法。 8. 冷冻法 温度降到零下18℃时海水会结冰。对制盐来说，去掉冰就等于盐田法的蒸发。温度不断降低，会结晶出不同的物质。在零下22.4℃之前将固体和海体分开，就可以得到纯净的氯化钠结晶。

氯化钠溶解度是多少？为什么氯化钠在水中的溶解度随温度变化不大？
2019-07-01 10:02:41
氯化钠 (Sodium chloride)，化学式NaCl,无色立方结晶或细小结晶粉末，味咸。外观是白色晶体状，其来源主要是海水，是食盐的主要成分。易溶于水、甘油，微溶于乙醇（酒精）、液氨；不溶于浓盐酸。不纯的氯化钠在空气中有潮解性。稳定性比较好，其水溶液呈中性，工业上一般采用电解饱和氯化钠溶液的...
