Antimony(III) acetate is the compound of antimony with the chemical formula of Sb(CH 3 CO 2) 3. It is a white powder, is moderately water-soluble, and is used as a catalyst in the production of polyesters .
Antimony(III) oxide is the inorganic compound with the formula Sb 2 O 3. It is the most important commercial compound of antimony. It is found in nature as the minerals valentinite and senarmontite. [3] Like most polymeric oxides, Sb 2 O 3 dissolves in aqueous solutions with hydrolysis. A mixed arsenic-antimony oxide occurs in nature as the ...
2 Sb + 3 S → Sb 2 S 3. Sb 2 S 3 is precipitated when H 2 S is passed through an acidified solution of Sb(III). [9] This reaction has been used as a gravimetric method for determining antimony, bubbling H 2 S through a solution of Sb(III) compound in hot HCl deposits an orange form of Sb 2 S 3 which turns black under the reaction conditions.

When part of a salt, the formula of the acetate ion is written as CH 3 CO − 2, C 2 H 3 O − 2, or CH 3 COO −. Chemists often represent acetate as OAc − or, less commonly, AcO −. Thus, HOAc is the symbol for acetic acid, NaOAc for sodium acetate, and EtOAc for ethyl acetate [1] (as Ac is common symbol for acetyl group CH 3 CO [2] [3]).
Also known as Sb 2 O 3. It has a melting point of 656 °C, and a boiling point of 1550 °C. It has a melting point of 656 °C, and a boiling point of 1550 °C. It is a Cubic Crystal Structure with a density of 5.2G/Cm3
The molecular formula C 2 H 2 O 3 (molar mass: 74.04 g/mol, exact mass: 74.0004 u) may refer to: Formic anhydride , or methanoic anhydride Glyoxylic acid , or oxoacetic acid
Antimony(III) sulfate was first produced in 1827 by the reaction of antimony(III) oxide and 18 molar sulfuric acid at 200 °C: [1]. Sb 2 O 3 + 3 H 2 SO 4 → Sb 2 (SO 4) 3 + 3 H 2 O. The concentration of the sulfuric acid is important, as a lower concentration will produce basic antimony oxides, while a higher concentration will produce antimony(III) pyrosulfate.
In solid SbF 3, the Sb centres have octahedral molecular geometry and are linked by bridging fluoride ligands. Three Sb–F bonds are short (192 pm) and three are long (261 pm). Because it is a polymer, SbF 3 is far less volatile than related compounds AsF 3 and SbCl 3. [3] SbF 3 is prepared by treating antimony trioxide with hydrogen fluoride: [4]
