It is one of the most common water-soluble salts of barium. Like most other water-soluble barium salts, it is a white powder, highly toxic, and imparts a yellow-green coloration to a flame. It is also hygroscopic, converting to the dihydrate BaCl 2 ·2H 2 O, which are colourless crystals with a bitter salty taste. It has limited use in the ...
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 carbonate is widely used in the ceramics industry as an ingredient in glazes. It acts as a flux, a matting and crystallizing agent and combines with certain colouring oxides to produce unique colours not easily attainable by other means.
The water-soluble barium sulfide is the starting point for other compounds: treating BaS with oxygen produces the sulfate, with nitric acid the nitrate, with aqueous carbon dioxide the carbonate, and so on. [9]: 6 The nitrate can be thermally decomposed to yield the oxide.
The solubility of a specific solute in a specific solvent is generally expressed as the concentration of a saturated solution of the two. [1] Any of the several ways of expressing concentration of solutions can be used, such as the mass, volume, or amount in moles of the solute for a specific mass, volume, or mole amount of the solvent or of the solution.
A metal ion in aqueous solution or aqua ion is a cation, dissolved in water, of chemical formula [M(H 2 O) n] z+.The solvation number, n, determined by a variety of experimental methods is 4 for Li + and Be 2+ and 6 for most elements in periods 3 and 4 of the periodic table.
Calcium chloride is a highly soluble calcium salt. Hexahydrate calcium chloride (CaCl 2 ·6H 2 O) has solubility in water of 811 g/L at 25 °C. [1] Calcium chloride when taken orally completely dissociates into calcium ions (Ca 2+) in the gastrointestinal tract, resulting in readily bioavailable calcium. The high concentration of calcium ions ...
Barium fluoride is an inorganic compound with the formula Ba F 2.It is a colorless solid that occurs in nature as the rare mineral frankdicksonite. [9] Under standard conditions it adopts the fluorite structure and at high pressure the PbCl 2 structure. [10]
