  2. Iron(III) chloride - Wikipedia

    en.wikipedia.org/wiki/Iron(III)_chloride

    Anhydrous iron(III) chloride has the BiI 3 structure, with octahedral Fe(III) centres interconnected by two-coordinate chloride ligands. [7] [10] Iron(III) chloride has a relatively low melting point and boils at around 315 °C. The vapor consists of the dimer Fe 2 Cl 6, much like aluminium chloride.

  3. Iron(II) chloride - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_chloride

    Ferrous chloride is prepared by addition of iron powder to a solution of hydrochloric acid in methanol. This reaction gives the methanol solvate of the dichloride, which upon heating in a vacuum at about 160 °C converts to anhydrous FeCl 2 . [ 4 ]

  4. Aluminium chloride - Wikipedia

    en.wikipedia.org/wiki/Aluminium_chloride

    Anhydrous aluminium chloride is a powerful Lewis acid, capable of forming Lewis acid-base adducts with even weak Lewis bases such as benzophenone and mesitylene. [14] It forms tetrachloroaluminate ([AlCl 4] −) in the presence of chloride ions. Aluminium chloride reacts with calcium and magnesium hydrides in tetrahydrofuran forming ...

  5. Iron(II) sulfate - Wikipedia

    en.wikipedia.org/wiki/Iron(II)_sulfate

    Thermolysis of iron(II) sulfate begins at about 680 °C (1,256 °F). 2 FeSO 4 Fe 2 O 3 + SO 2 + SO 3. Like other iron(II) salts, iron(II) sulfate is a reducing agent. For example, it reduces nitric acid to nitrogen monoxide and chlorine to chloride: 6 FeSO 4 + 3 H 2 SO 4 + 2 HNO 3 → 3 Fe 2 (SO 4) 3 + 4 H 2 O + 2 NO

  6. Tetrakis(methylammonium) hexachloroferrate(III) chloride

    en.wikipedia.org/wiki/Tetrakis(methylammonium...

    The compound is synthesised by reacting methylammonium chloride, CH 3 NH 3 Cl, with anhydrous iron(III) chloride and adding hydrochloric acid with heating. Crystals of the product, which precipitate as the solvent evaporates, are collected and dried using vacuum desiccation. [2]

    Soon, with five people in the room—Townsell, her boyfriend, a patient-care advocate, the supervising doctor, and a doctor in training—the doctor used the Carevix to place her copper IUD.

  8. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    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.
