Cov Khoom Siv Physicochemical ntawm Sodium Sulphide:
Daim ntawv anhydrous yog ib qho khoom siv dawb crystalline uas yog deliquescent heev. Nws muaj qhov ceev ntawm 1.856 (ntawm 14 ° C) thiab lub ntsiab lus yaj ntawm 1180 ° C. Sodium Sulphide yaj tau hauv dej (solubility: 15.4 g / 100 ml ntawm 10 ° C; 57.2 g / 100 ml ntawm 90 ° C). Nws reacts nrog acids los tsim hydrogen sulfide. Nws yog me ntsis soluble hauv cawv thiab insoluble hauv ether. Nws cov kua dej yog alkaline heev, yog li nws tseem hu ua sulfide alkali. Nws yaj sulfur los ua sodium polysulfide. Cov khoom lag luam-qib feem ntau tshwm sim ua xim liab, xim av liab, lossis xim av daj vim muaj cov khoom tsis huv. Sodium Sulphide yog corrosive thiab lom. Nws yooj yim oxidizes hauv huab cua los ua sodium thiosulfate.
