1.将本品垂直放于1升的容量瓶上。
解毒药:硫代硫酸钠是一种供硫剂，具有活泼的硫原子，通过硫转移酶，能与体内游离的或已与高铁血红蛋白结合的CN-结合，使其变为毒性很小的
物理性质:硫代硫酸钠有无水硫代硫酸钠 (Na2S2O3) 和五水硫代硫酸钠 (Na2S2O3·5H2O)两种，后者又称大苏打和海波。分子量分别为158.11和248.18。无水硫代硫酸钠为不透明的结晶粉末。相对密度 1.667。无臭，味咸。易溶于水，不溶于乙醇。在酸性溶液中分解。具有较强的还原性。极易吸潮。五水合硫代硫酸钠为无臭、无色透明的单斜晶体或颗粒。相对密度1.685。熔点48℃。 100℃时失去全部结晶水，高于100℃时分解。在干热空气中易风化。在湿热空气中轻度潮解。易溶于水和松节油; 不溶于乙醇。遇强酸时分解。长时间暴露于空气中易被氧和二氧化碳氧化和碳化。
无臭，味咸。易溶于水，100℃时溶解度23lg/100ml水。不溶于醇。空气中易潮解。具有强烈的还原性，在酸性溶液中分解。加热即分解
防护措施:纯碱粉尘对皮肤、呼吸道和眼睛有刺激作用。长时间接触纯碱溶液可能出现湿疹、皮炎等。其浓溶液可引起烧伤、坏死，以至角膜浑浊。空气中纯碱粉尘最高容许浓度为2mg/m3。操作人员应穿戴工作服、口罩、手套，长统靴等劳保用品，以保护呼吸器官和皮肤。

化工原料:硫代硫酸钠俗名海波或大苏打，是一种常用的化工原料，在照相、电影和印刷制版业中作定影剂。在制革中用作还原剂。在造纸和纺织业中，用以除去残留的漂白剂和用作媒染剂。在医学上用作氰化物中毒的解毒剂等。在水处理中，用作饮用水和废水的脱氯剂，杀菌剂; 循环冷却水的铜缓蚀剂; 以及锅炉水系统的脱氧剂。还用于含氰化物废水的处理等。工业上一般以纯碱和硫磺为原料，使纯碱与燃烧硫磺产生的二氧化硫反应制得亚硫酸钠，再加入硫磺进行沸腾反应，然后，经过滤、脱色、浓缩和结晶等操作，即可得到硫代硫酸钠五水物。也可利用其他生产的含硫化钠、亚硫酸钠、硫磺和氢氧化钠的废料，经适当处理后得到产品。以上信息有Chemicalbook的Andy编辑整理。
