Tin(II) sulfide is an inorganic compound with the chemical formula is SnS. A black or brown solid, it occurs as the rare mineral herzenbergite (α-SnS).It is insoluble in water but dissolves with degradation in concentrated hydrochloric acid. Tin(II) sulfide is insoluble in ammonium sulfide.
Tin sulfide can refer to either of these chemical compounds: Tin(II) sulfide, SnS; Tin(IV) sulfide, SnS 2 This page was last edited on 2 December ...
Sulfides of tin exist in both the +2 and +4 oxidation states: tin(II) sulfide and tin ... (formula: R 2 Sn, as seen for singlet carbenes) and distannylenes (R 4 Sn 2
Tin(II) sulfate (Sn S O 4) is a chemical compound. It is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate: [3] Sn (s) + CuSO 4 (aq) → Cu (s) + SnSO ...

It also reduces copper(II) to copper(I). Solutions of tin(II) chloride can also serve simply as a source of Sn 2+ ions, which can form other tin(II) compounds via precipitation reactions. For example, reaction with sodium sulfide produces the brown/black tin(II) sulfide: SnCl 2 (aq) + Na 2 S (aq) → SnS (s) + 2 NaCl (aq)
The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Tin(IV) sulfide is a compound with the formula SnS2. A brown, water-insoluble solid, it is a semiconductor with band gap 2.2 eV. [ 5 ] It occurs naturally as the rare mineral berndtite .
