The paper is burned off in a muffle furnace, the resulting barium sulfate is weighed, and the purity of the sulfate compound is thus calculated. In industry, barium chloride is mainly used in the purification of brine solution in caustic chlorine plants and also in the manufacture of heat treatment salts, case hardening of steel . [ 7 ]
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.

Aluminium sulfate may be used as a deodorant, an astringent, or as a styptic for superficial shaving wounds. [citation needed] Aluminium sulfate is used as a mordant in dyeing and printing textiles. It is a common vaccine adjuvant and works "by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation."
Coloured flames of methanol solutions of different compounds, burning on cotton wool. From left to right: lithium chloride, strontium chloride, calcium chloride, sodium chloride, barium chloride, trimethyl borate, copper chloride, cesium chloride and potassium chloride. Some common elements and their corresponding colors are:
Aluminium arsenate – AlAsO 4 [6] Aluminium arsenide – AlAs [7] [8] Aluminium diboride – AlB 2 [9] [10] Aluminium bromide – AlBr 3 [11] Aluminium carbide – Al 4 C 3 [12] Aluminium iodide – AlI 3 [13] Aluminium nitride – AlN [14] Aluminium oxide – Al 2 O 3 [15] Aluminium phosphide – AlP [16] Aluminium chloride – AlCl 3 [17 ...
Barium reacts with ammonia to form the electride [Ba(NH 3) 6](e-) 2, which near room temperature gives the amide Ba(NH 2) 2. [11] The metal is readily attacked by acids. Sulfuric acid is a notable exception because passivation stops the reaction by forming the insoluble barium sulfate on the surface. [12]
Barium sulfate (or sulphate) is the inorganic compound with the chemical formula Ba SO 4. It is a white crystalline solid that is odorless and insoluble in water . It occurs in nature as the mineral barite , which is the main commercial source of barium and materials prepared from it.
