Barium nitrate
Solid crystalline the white substance, sparingly soluble in water (9.2 g/100 ml at 20 C), the melting point is equal to 595 C.
Barium nitrate BA(NO3)2 (barium nitrate) in the technique obtained in various ways. The easiest way to do this dissolving witherite in Vases nitric acid. Instead ВаСО3 can be based on iron Was obtained recovery of heavy spar ВаЅО4; in the last case released by the reaction of the hydrogen sulfide capture, passing it through sodium hydroxide.
Barium nitrate is soluble in water much harder than the nitrates of other alkaline earth metals. In alcohol it is almost insoluble. Its solubility in water is at: 10 °C 7; 20 °C to 9.2; 100 °C to 32.2 g of BA(NO3)2 in 100 g of water. Below 12 ºC and sustained contact with the solution is dihydrate BA(NO3)2∙2Н2О. At ordinary temperatures the barium nitrate kristallizuetsya in an anhydrous condition, forming octahedra specific weight of 3.24, melting at 575 °C. for baloe high heat BA(NO3)2 first cleaves the oxygen, turning into nitrite and only with vigorous calcination the formation of oxide.
Of barium nitrate to get pure oxide and hydroxide barium; it is also used to obtain vedeste explosives, and in pyrotechnics for the production of green sparklers.
