Gas Introduction

Hydrogen sulfide is an inorganic compound with the chemical formula H2S and a molecular weight of 34.076. It is a flammable acidic gas under standard conditions. It is colorless and has the smell of rotten eggs at low concentrations. It has a sulfur smell at extremely low concentrations and is highly toxic. Its aqueous solution is hydrosulfuric acid, which is weaker in acidity than carbonic acid but stronger than boric acid. It is soluble in water and easily soluble in alcohols, petroleum solvents and crude oil.

Hydrogen sulfide is a flammable hazardous chemical. It can form an explosive mixture when mixed with air and can cause combustion and explosion when exposed to open flames and high heat. Hydrogen sulfide is an important chemical raw material.
