Ubuhanga bwa H2S. Twifashishije ibintu 3 byingenzi bya molekile ya H2S mugihe cyo kugabanya H2S.

H2S ni gaze ya acide kandi izashyira umunyu amine kuri hydrosulphide ya aminium. Igisubizo ariko kirahindurwa kandi kigize ishingiro ryurwego rwo gutunganya amine; umunyu ugabanywa gusubira H2S na amine yubusa kubushyuhe. Iyi nzira kandi ikuraho CO2 kuko nayo ari gaze ya aside.

H2S nigikorwa cyo kugabanya bityo irashobora guhita ihinduka okiside. Imiterere ya sulfure ni -2 muri H2S kandi irashobora kuba okiside kuri 0, sulfure yibanze (urugero: alkaline sodium nitrite cyangwa hydrogen peroxide) cyangwa +6, sulfate na dioxyde ya chlorine, hypohalite nibindi.

H2S ni nucleophile ikomeye bitewe na atome ya sulfuru ikaba yoroshye ya Lewis. Electron ziri mumashanyarazi 3 ya elegitoronike, kure ya nucleus, igendanwa cyane kandi yimuwe byoroshye. Urugero rwiza rwibi ni uko H2O ari amazi afite amazi abira 100 C mugihe H2S, molekile iremereye, ni gaze ifite aho itetse -60 C. Umutungo wa Lewis ukomeye wa atome wa ogisijeni ukora hydrogène ikomeye cyane inkwano, kurenza H2S, niyo mpamvu itandukaniro rinini ritetse. Ubushobozi bwa nucleophilique ya atome ya sulfuru bukoreshwa mugukora hamwe na triazine, formaldehyde na hemiformal cyangwa formaldehyde irekura, acrolein na glyoxal.
