Aluminum Sulfide Formula
How is Aluminum Sulfide Prepared
Its synthesis via straight heating of aluminum and sulhair have the right to be stood for by the complying with equation <7>:
2Al + 3S → Al2S3
However before, the reactivity is extremely exothermic, and also it is not preferable to warmth the whole mixture <7>. Also, sulhair is a volatile reactant that melts ameans before the reactivity takes location <7>. Thus, lead sulfide is often supplied for the preparation of Al2S3 <7>:
2Al + 3PbS → Al2S3 + 3Pb
Reactions via Other Compounds
Aluminum Sulfide and Water
When aluminum sulfide is exposed to moisture in the environment, it undergoes hydrolysis reactivity to create aluminum hydroxide and also hydrogen sulfide <5>.
Al2S3 + 6H2O → 2Al(OH)3 + 3H2S
Aluminum Sulfide and Hydrochloric Acid
Aluminum sulfide upon reacting via hydrochloric acid forms hydrogen sulfide and aluminum chloride, as presented below <8>:
Al2S3 + 6HCl → 2AlCl3 + 3H2S
