氯化钠 用途与合成方法
水中溶解度(g/100ml) 不同温度(℃)时每100毫升水中的溶解克数:
35.7g/0℃;35.8g/10℃;35.9g/20℃;36.1g/30℃;36.4g/40℃
37.1g/60℃;38g/80℃;38.5g/90℃;39.2g/100℃
鉴别试验 钠盐及氯化物试验(IT-28及IT-12)阳性。
含量分析 准确称取预经在625℃下干燥2h后的试样约250mg,放入一具玻塞烧瓶中,加水50ml溶解。在搅拌下加入硝酸3ml、硝基苯5ml、0.1mol/L硝酸银50.0ml和硫酸铁铵试液(TS-99)2ml。充分摇震后用0.1mol/L硫氰酸铵滴定过量的硝酸银。每Ml0.1mol/L硝酸银相当于氯化钠(NaCl)5.844mg。
毒性 LD503000mg/kg(大鼠,经口)。
