WebCes métaux - béryllium, magnésium, calcium et strontium - réagissent avec l'acide chlorhydrique pour former un chlorure et de l'hydrogène libre. Le magnésium métallique combiné à l'acide chlorhydrique produira naturellement du chlorure de magnésium - utilisé comme complément alimentaire - et dégagera de l'hydrogène sous forme gazeuse. Web(reaction 3) is possible, which will be hydrolyzed to hematite (reaction 4). It follows that in the presence of oxygen the resultant reaction of high-tempera-ture hydrolysis of FeCl 2 ×4H 2 O will be reaction 5, producing a mixture of powders of magnetite and hematite, hydrochlo-ric acid and water vapor.
