Hlau sulfide yog cov tshuaj sib xyaw FeS , dub tawv. Nws yog tsim los ntawm hlau thiab sulfide ions. FeS muaj hlau nyob rau hauv nws +2 oxidation xeev. Nws reacts nrog acids xws li hydrochloric acid ua hydrogen sulfide gas.
Ib yam li ib tug yuav nug, puas yog hlau sulfide khoom?
Hlau (III) sulfide , tseem hu ua ferric sulfide los yog sesquisulfide, yog ib qho ntawm peb hlau sulfides Tsis tas li ntawd FeS thiab FeS2. Nws yog ib khov kho , dub hmoov tab sis decays ntawm ambient kub mus rau hauv ib tug daj-ntsuab hmoov. Qhov no yog ib yam khoom uas tsis ruaj khov uas tsis tshwm sim hauv qhov xwm txheej.
Tsis tas li ntawd, hlau sulfide zoo li cas? Hlau yog ib tug silvery grey xim, Sulfur yog xim daj. Tom qab cov tshuaj tiv thaiv tshuaj (kub), ob lub ntsiab lus, Hlau thiab Sulfur, yog chemically koom ua ke los tsim Hlau sulfide , uas yog qhov sib xyaw. Lub cim rau qhov sib xyaw no yog FeS, thiab cov khoom Hlau sulfide yog xim hlau xim dub.
Ib yam li ntawd, koj tuaj yeem nug, yog hlau sulfide aqueous?
Qee qhov hydrogen sulfide yuav hnov mob nrog hlau ions nyob rau hauv dej los yog khoom tsim hlau los yog hlau sulfides uas tsis yog dej, soluble . Cov hlau no sulfides , zoo li hlau (II) sulfide , feem ntau yog xim dub los yog xim av, ua rau cov xim sludge.
Puas yog hlau sulfide ntab los yog dab dej?
Hlau (II) sulfide yog xim av tawv. LOSSIS Peb tuaj yeem ntxiv dilute hydrochloric acid rau hauv cov raj kuaj. Sulfur ntab nyob rau saum cov kua qaub. Hlau dab dej thiab muab cov npuas uas tsis muaj xim.

Cov roj twg yog hloov zuj zus thaum hlau sulfide kho nrog dilute sulfuric acid?
Thaum hlau sulfide reacts nrog diluted sulfuric acid, hydrogen sulfide yog tsim uas yog sau nyob rau hauv lub hub gas los ntawm upward tsiv ntawm huab cua
