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 ...
2 ·12H 2 O. An alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula X Al(SO 4) 2 ·12 H 2 O, such that X is a monovalent cation such as potassium or ammonium. [1] By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2 ·12 H 2 O.
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 ...
Mark is the only gospel with the combination of verses in Mark 4:24–25: the other gospels split them up, Mark 4:24 being found in Luke 6:38 and Matthew 7:2, Mark 4:25 in Matthew 13:12 and Matthew 25:29, Luke 8:18 and Luke 19:26.

so whats the formula? KAl(SO4)2·12(H2O) or K2SO4·Al2(SO4)3·24H2O ? mastodon 17:22, 29 May 2006 (UTC) If you look closely you'll see that the second formula is the first one doubled and rearranged, so they have the same proportions. It is confusing though; I'll try to improve it. —Keenan Pepper 04:31, 2 June 2006 (UTC)
