Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). ?) Iron (III) chromate is the iron (III) salt of chromic acid with the chemical formula Fe2(CrO4)3.
The chromate and dichromate ions are fairly strong oxidizing agents. Commonly three electrons are added to a chromium atom, reducing it to oxidation state +3. In acid solution the aquated Cr 3+ ion is produced. Cr. 2O2−. 7 + 14 H + + 6 e − → 2 Cr 3+ + 7 H 2 O ε0 = 1.33 V.
Ferric oxalate, also known as iron (III) oxalate, refers to inorganic compounds with the formula Fe2(C2O4)3 (H 2 O) x but could also refer to salts of [Fe (C2O4)3]3-. Fe2(C2O4)3 (H 2 O) x are coordination polymers with varying degrees of hydration. The coordination complex with the formula [Fe (C2O4)3]3- forms a variety of salts, a well-known ...
Iron (II) chloride tetrahydrate, FeCl2·4H2O. In chemistry, iron (II) refers to the element iron in its +2 oxidation state. The adjective ferrous or the prefix ferro- is often used to specify such compounds, as in ferrous chloride for iron (II) chloride (FeCl2). The adjective ferric is used instead for iron (III) salts, containing the cation Fe 3+.
The iron compounds produced on the largest scale in industry are iron(II) sulfate (FeSO 4 ·7H 2 O) and iron(III) chloride (FeCl 3). The former is one of the most readily available sources of iron(II), but is less stable to aerial oxidation than Mohr's salt ((NH 4) 2 Fe(SO 4) 2 ·6H 2 O). Iron(II) compounds tend to be oxidized to iron(III ...
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.
Ferric. Potassium ferrioxalate contains the iron (III) complex [Fe (C2O4)3]3−. In chemistry, iron (III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron (III) chloride (FeCl3). The adjective ferrous is used instead for iron (II) salts, containing the cation Fe 2+.
Iron (III) oxide in a vial. Iron (III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It occurs in nature as the mineral hematite, which serves as the primary source of iron for the steel industry. It is also known as red iron oxide, especially when used in pigments.
