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.

Barium acetate is generally produced by the reaction of acetic acid with barium carbonate: [2] BaCO 3 + 2 CH 3 COOH → (CH 3 COO) 2 Ba + CO 2 + H 2 O. The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium ...
Each Ba 2+ center is bound by two water ligands and six hydroxide ligands, which are respectively doubly and triply bridging to neighboring Ba 2+ centre sites. [4] In the octahydrate, the individual Ba 2+ centers are again eight coordinate but do not share ligands. [5] Coordination sphere about an individual barium ion in Ba(OH) 2.H 2 O.

Barium metaphosphate is an inorganic substance with the molecular formula Ba(PO 3) 2. It is a colourless solid that is insoluble in water, though is soluble in acidic solutions through "slow dissolution". [3] X-ray crystallography shows that this material is composed of Ba 2+ cations attached to a polyphosphate ((PO 3 −) n) anion. [4]
Its chemical formula is usually expressed as Pb(CH 3 COO) 2 or Pb(OAc) 2, where Ac represents the acetyl group. Like many other lead compounds, it causes lead poisoning. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(OAc) 2 ·3H 2 O, a colourless or white efflorescent monoclinic crystalline substance.
½ O 2 (g) + O 2– O ⇌ [O 2] 2– O. where J O is the species J in the oxygen position within the rock-salt lattice. The complete peroxidation of BaO to BaO 2 occurs at moderate temperatures by oxygen uptake within the BaO rock-salt lattice: Barium oxide peroxidation from oxygen uptake, adapted from Middleburgh et al, 2012.
