Kev Ua Haujlwm
Chemical equation: 2NaOH+H2S=NA2S+2H2O
NA2S + H2S = 2NAHS
Thawj kauj ruam: Siv sodium hydroxide kua nqus hydrogen sulfide tsim sodium sulphide
Kauj ruam thib ob: Thaum sodium sulfide nqus saturation, txuas ntxiv nqus hydrogen sulfide tsim sodium hydrosulphide.
Sodium hydrosulfide muaj 2 hom tsos, 70% min daj flake thiab 30% yellowsih kua.
Peb muaj cov specs sib txawv uas nyob ntawm Fe cov ntsiab lus, peb muaj 10ppm, 15ppm, 20ppm thiab 30ppm.Different Fe cov ntsiab lus, qhov zoo sib txawv.
