Arsenic pentasulfide is prepared by precipitation from an acidic solution of soluble As(V) salts by treatment with hydrogen sulfide. [3] It may be also prepared by heating a mixture of arsenic and sulfur, extracting the fused mass with an ammonia solution and reprecipitating arsenic pentasulfide at low temperature by addition of hydrochloric acid.
Arsenic sulfide may refer to: Arsenic trisulfide , As 2 S 3 , the mineral orpiment Arsenic pentasulfide , As 2 S 5 , similar structure to phosphorus pentasulfide (β-P 2 S 5 )
Arsenic trioxide powder.. Compounds of arsenic resemble in some respects those of phosphorus which occupies the same group (column) of the periodic table.The most common oxidation states for arsenic are: −3 in the arsenides, which are alloy-like intermetallic compounds, +3 in the arsenites, and +5 in the arsenates and most organoarsenic compounds.

Ammonium pentasulfide is a chemical compound with the chemical formula (NH 4) 2 S 5. [1] Synthesis.
Phosphorus sulfides comprise a family of inorganic compounds containing only phosphorus and sulfur.These compounds have the formula P 4 S n with n ≤ 10. Two are of commercial significance, phosphorus pentasulfide (P 4 S 10), which is made on a kiloton scale for the production of other organosulfur compounds, and phosphorus sesquisulfide (P 4 S 3), used in the production of "strike anywhere ...
Arsenic trisulfide is the inorganic compound with the formula As 2 S 3. It is a dark yellow solid that is insoluble in water. It is a dark yellow solid that is insoluble in water. It also occurs as the mineral orpiment (Latin: auripigmentum), which has been used as a pigment called King's yellow.
