Hydrogen grooving sulfuric acid
Web21 aug. 2024 · Making hydrogen chloride. When concentrated sulfuric acid is added to sodium chloride under cold conditions, the acid donates a proton to a chloride ion, forming hydrogen chloride. In the gas phase, it immediately escapes from the system. (1) C l − + H 2 S O 4 → H C l + H S O 4 −. The full equation for the reaction is: WebBiogenic sulfide corrosion is a bacterially mediated process of forming hydrogen sulfide gas and the subsequent conversion to sulfuric acid that attacks concrete and steel within …
