H2s acts as
WebH2S acts only as reducing agent while SO2 can act both as reducing agent and oxidising agent. Why is H2S a reducing agent? In H2S the oxidation state of Sulphur is -2 so it can loss electron to attain +4 and +6 oxidation state but it can not gain the electron. Therefore H2S act as reducing agent. … WebJul 11, 2024 · Hydrogen sulfide (H 2 S) is widely considered the third endogenous gaseous transmitter, accompanying carbon monoxide and nitric oxide 1, and plays important roles …
