Cov Khoom ntawm Sodium Sulfide
Cov mis tshuaj: Na₂S
Qhov Hnyav Molecular: 78.04
Cov Qauv thiab Cov Khoom Siv
Sodium sulfide yog hygroscopic heev. Nws yooj yim soluble hauv dej, me ntsis soluble hauv ethanol, thiab insoluble hauv ether. Nws cov kua dej yog alkaline heev thiab tuaj yeem ua rau kub hnyiab thaum kov daim tawv nqaij lossis plaub hau. Yog li ntawd, sodium sulfide feem ntau hu ua sulfide alkali. Nws oxidizes yooj yim hauv huab cua thiab reacts nrog cov kua qaub muaj zog kom tso tawm hydrogen sulfide roj. Nws tuaj yeem tsim cov hlau sulfide insoluble thaum reacts nrog ntau yam tshuaj ntsev hnyav.

Sodium sulfide muaj daim ntawv pov thawj SGS thib peb, daim ntawv pov thawj qib kev lag luam, thiab tau dhau daim ntawv pov thawj ISO thoob ntiaj teb zoo system thiab daim ntawv pov thawj REACH ua raws li txoj cai. Nyem qhov no kom tau txais tus nqi luv nqi.
