Cov khoom siv lub cev ntawm sodium hydrosulfide yog dab tsi?
Cov Khoom Siv Physicochemical ntawm sodium hydrosulfide Kev daws teeb meem
(1)Tshwm sim ua cov xim tsis muaj xim zoo li koob siv lead ua hauv daim ntawv ntshiab, uas yog deliquescent, hygroscopic heev, thiab yooj yim oxidized. Kev khaws cia feem ntau ua rau muaj hydrogen sulfide thiab sulfur tso tawm. Cov khoom lag luam feem ntau yog cov kua, zoo li txiv kab ntxwv lossis daj, nrog rau saj iab.
(2) Zoo heev nyob rau hauv dej thiab cawv. Cov kua dej yog alkaline heev. Nws lwj thaum nws kov cov kua qaub, ua rau muaj hydrogen sulfide (piv txwv li, nws ua rau HCl ua rau muaj H₂S).
(3) Yooj yim hydrolyzes nyob rau hauv huab cua noo noo los tsim sodium hydroxide thiab hydrogen sulfide.
Cov Khoom Siv Tsis Sib Xws: Cov neeg sawv cev oxidizing muaj zog, cov kua qaub, zinc, txhuas, tooj liab, thiab lawv cov alloys.
