And the acid preparation in two stages, the first through the interaction of both gaseous hydrogen and chlorine under temperature greater than 250 degrees Celsius, with humidity as a catalyst working to speed up the reaction to form gas (HCl), through the equation H2 + Cl2 → 2HCl, or can be prepared through integration of sodium chloride with sulfuric acid, or through a chlorine reaction with methane and benzene, and after gas preparation (HCl), is dissolved in the water to prepare hydrochloric acid. [1] It is noteworthy that hydrochloric acid is produced in the body by cells to help the stomach digest food. [2]
