  2. Aluminium sulfate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_sulfate

    Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al 2 (SO 4) 3 ·16H 2 O and octadecahydrate Al 2 (SO 4) 3 ·18H 2 O are the most common. The heptadecahydrate, whose formula can be written as [Al(H 2 O) 6] 2 (SO 4) 3 ·5H 2 O, occurs naturally as the ...

    en.wikipedia.org/wiki/Potassium_alum

    It is commonly encountered as the dodecahydrate, KAl(SO 4) 2 ·12H 2 O. It crystallizes in an octahedral structure in neutral solution and cubic structure in an alkali solution with space group Pa 3 and lattice parameter of 12.18 Å. [4] The compound is the most important member of the generic class of compounds called alums, and is often ...

    en.wikipedia.org/wiki/Aluminium_compounds

    A stable derivative of aluminium monoiodide is the cyclic adduct formed with triethylamine, Al 4 I 4 (NEt 3) 4. Also of theoretical interest but only of fleeting existence are Al 2 O and Al 2 S. Al 2 O is made by heating the normal oxide, Al 2 O 3 , with silicon at 1,800 °C (3,272 °F) in a vacuum .

    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.

  7. Ammonium iron(III) sulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iron(III)_sulfate

    Ammonium iron(III) sulfate, NH 4 Fe(SO 4) 2 ·12 H 2 O, or NH 4 [Fe(H 2 O) 6](SO 4) 2 ·6 H 2 O, also known as ferric ammonium sulfate (FAS) or iron alum, is a double salt in the class of alums, which consists of compounds with the general formula AB(SO 4) 2 · 12 H 2 O. [2] It has the appearance of weakly violet, octahedrical crystals.

    en.wikipedia.org/wiki/Sodium_aluminate

    Other related compounds, sometimes called sodium aluminate, prepared by reaction of Na 2 O and Al 2 O 3 are Na 5 AlO 4 which contains discrete AlO 4 5− anions, Na 7 Al 3 O 8 and Na 17 Al 5 O 16 which contain complex polymeric anions, and NaAl 11 O 17, once mistakenly believed to be β-alumina, a phase of aluminium oxide.

  9. Aluminium dihydrogenphosphate - Wikipedia

    en.wikipedia.org/wiki/Aluminium_dihydrogenphosphate

    Aluminium dihydrogenphosphate describes inorganic compounds with the formula Al(H 2 PO 4) 3. xH 2 O where x = 0 or 3. They are white solids. Upon heating these materials convert sequentially to a family of related polyphosphate salts including aluminium triphosphate (AlH 2 P 3 O 10. 2H 2 O), aluminium hexametaphosphate (Al 2 P 6 O 18), and aluminium tetrametaphosphate (Al 4 (P 4 O 12) 3).
