醋酸铅试纸主要用于检验硫化氢气体的存在.润湿的醋酸铅试纸遇到硫化氢气体时,产生硫化铅.白色的试纸立即变黑.化学方程式是:Pb(CH3COO)2＋H2S=PbS↓＋2CH3COOH.醋酸铅试纸非常灵敏,必须把试纸保存在密封、干净的广口试剂瓶里.使用时要用干净的镊子夹取.试纸用水润湿后要立即悬放在盛放硫化氢气体的容器中.主要用于检验硫化氢气体的存在

Lead acetate test paper is mainly used for testing the presence of hydrogen sulfide gas,moistened lead acetate test paper encountered hydrogen sulfide gas to produce white paper lead sulfide immediately darkened,chemical equation:Pb(CH3COO)2＋H2S=PbS↓＋2CH3COOH.Lead acetate paper is very sensitive,it must be kept in a sealed,clean wide-mouth reagent bottle.When using clean forceps after wet paper with water immediately suspended on housing containers of hydrogen sulfide gas.
● Instant pH readings
● Accurate for a wide range of routine pH testing
● The minimum detection limit:5 mg/l S2-
● Convenient and portable for field use
