Cov Khoom Siv Tshuaj ntawm Sodium Hydrosulfide
Nov yog kev txhais lus Askiv zoo ntawm cov khoom siv tshuaj lom neeg ntawm sodium hydrosulfide:
Cov Khoom Siv Tshuaj ntawm Sodium Hydrosulfide:
Sodium hydrosulfide ruaj khov nyob rau hauv qhov kub thiab txias ib txwm muaj. Nws yaj tau zoo heev hauv dej thiab cawv, tsim cov kua qaub alkaline heev. Thaum kov cov kua qaub, nws lwj, tso tawm. hydrogen sulfide (H₂S).
Cov khoom lag luam feem ntau yog muab los ua cov kua txiv kab ntxwv lossis daj nrog saj iab. Nws yog hygroscopic heev thiab yooj yim nqus cov dej noo los ntawm huab cua. Nws yaj yooj yim hauv dej thiab ethanol.
Thaum twg ZOOnyob rau hauv huab cua qhuav, nws hloov daj lossis txiv kab ntxwv, thiab thaum yaj, nws dhau los ua dub. Reacting nroghydrochloric acid (HCl) tsim H₂S hauv qhov tshuaj tiv thaiv muaj zog. Vim nws muaj zog hygroscopicity, nws yooj yim rau oxidation thiab feem ntau tso tawm hydrogen sulfide thiab sulfur thaum lub sijhawm khaws cia.
