Ferric acetate is the iron compound with the formula Fe 3 O(O 2 CCH 3) 6 (H 2 O) 3]O 2 CCH 3. This red brown solid is the acetate salt of the coordination complex [Fe 3 O(OAc) 6 (H 2 O) 3] + (OAc − is CH 3 CO 2 −). Commonly, the salt is known as "basic iron acetate". [2] The formation of the red-brown complex was once used as a test for ...
Iron(II) acetate describes compounds with formula Fe(CH 3 CO 2) 2 ·(H 2 O) x where x can be 0 (anhydrous) or 4 (tetrahydrate). The anhydrous compound is a white solid, although impure samples can be slightly colored. [1] The tetrahydrate is light green solid that is highly soluble in water.
Iron(III) acetate (ferric acetate), [Fe 3 O(CH 3 CO 2 −) 6 (H 2 O) 3]CH 3 CO 2 −; Ferrous acetate (iron(II) acetate), Fe(CH 3 COO) 2; See also. kanemizu ...
Iron forms various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe 3 O 4), and iron(III) oxide (Fe 2 O 3). Iron(II) oxide also exists, though it is unstable at room temperature. Despite their names, they are actually all non-stoichiometric compounds whose compositions may vary. [12]
The acetate anion, [CH 3 COO] −,(or [C 2 H 3 O 2] −) is one of the carboxylate family. It is the conjugate base of acetic acid. Above a pH of 5.5, acetic acid converts to acetate: [1] CH 3 COOH ⇌ CH 3 COO − + H + Many acetate salts are ionic, indicated by their tendency to dissolve well in water.
A molecular ferric complex is the anion ferrioxalate, [Fe(C 2 O 4) 3] 3−, with three bidentate oxalate ions surrounding the Fe core. Relative to lower oxidation states, ferric is less common in organoiron chemistry , but the ferrocenium cation [Fe(C 2 H 5 ) 2 ] + is well known.
For example, for the compound FeCl 3, the cation, iron, can occur as Fe 2+ and Fe 3+. In order for the compound to have a net charge of zero, the cation must be Fe 3+ so that the three Cl − anions can be balanced (3+ and 3− balance to 0). Thus, this compound is termed iron(III) chloride. Another example could be the compound PbS 2.
Acetic anhydride, or ethanoic anhydride, is the chemical compound with the formula (CH 3 CO) 2 O.Commonly abbreviated Ac 2 O, it is the simplest isolable anhydride of a carboxylic acid and is widely used as a reagent in organic synthesis.
