Aluminum Sulfide Formula
How is Aluminum Sulfide Prepared
Its synthetic through direct heating the aluminum and sulfur can be represented by the complying with equation <7>:
2Al + 3S → Al2S3
However, the reaction is extremely exothermic, and it is not desirable to warmth the whole mixture <7>. Also, sulfur is a volatile reactant the melts away prior to the reaction takes ar <7>. Therefore, lead sulfide is frequently used because that the preparation of Al2S3 <7>:
2Al + 3PbS → Al2S3 + 3Pb
Aluminum Sulfide
Reactions with various other Compounds
Aluminum Sulfide and Water
When aluminum sulfide is exposed to moisture in the atmosphere, it undergoes hydrolysis reaction to form aluminum hydroxide and hydrogen sulfide <5>.
Al2S3 + 6H2O → 2Al(OH)3 + 3H2S
Aluminum Sulfide and Hydrochloric Acid
Aluminum sulfide top top reacting through hydrochloric acid develops hydrogen sulfide and aluminum chloride, together shown listed below <8>:
Al2S3 + 6HCl → 2AlCl3 + 3H2S
