Chemistry na H2S ragewa. Muna yin amfani da mahimman kaddarorin 3 na kwayoyin H2S yayin aiwatar da ragewar H2S.

H2S gas ne na acidic kuma zai yi gishiri da yawa amines zuwa aminium hydrosulphide. Halin yana iya jujjuya shi kuma ya zama tushen sashin sake amfani da amine; Gishirin da ake raba shi zuwa H2S da amine kyauta ta zafi. Wannan tsari kuma yana cire CO2 tunda shi ma iskar gas ne.

H2S wakili ne mai ragewa kuma don haka ana iya samun iskar oxygen cikin sauri. Halin valence na sulfur shine -2 a cikin H2S kuma ana iya samun iskar oxygen zuwa 0, sulfur elemental (misali alkaline sodium nitrite ko hydrogen peroxide) ko +6, sulfate ta chlorine dioxide, hypohalites da sauransu.

H2S ne mai ƙarfi nucleophile saboda sulfur atom wanda shine tushe Lewis mai laushi. Electrons suna cikin harsashi na lantarki guda 3, daga tsakiya, mafi wayar hannu kuma cikin sauƙi. Misali mai kyau na wannan shine gaskiyar cewa H2O ruwa ne mai tafasar maki 100 C yayin da H2S, kwayar halitta mai nauyi, iskar gas ce mai tafasa -60 C. Babban kayan Lewis mai wuyar iskar oxygen yana samar da hydrogen mai ƙarfi sosai. shaidu, fiye da H2S, don haka babban bambancin ma'anar tafasa. Ana amfani da yuwuwar nucleophilic na zarra na sulfur a cikin amsawa tare da triazine, formaldehyde da hemiformal ko formaldehyde releasers, acrolein da glioxal.
