IBarium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%
I-Barium hydroxide, i-chemical compound kunye ne-chemical formulaBa(OH)2, yinto emhlophe eqinileyo, enyibilikayo emanzini, isisombululo kuthiwa ngamanzi e-barite, i-alkaline eyomeleleyo.I-Barium Hydroxide inelinye igama, elithi: caustic barite, barium hydrate.I-monohydrate (x = 1), eyaziwa ngokuba yi-baryta okanye i-baryta-water, enye yeenqununu eziphambili ze-barium.Le monohydrate emhlophe yegranular yindlela eqhelekileyo yorhwebo.IBarium Hydroxide Octahydrate, njengomthombo we-crystalline we-crystalline we-crystalline ongenakunyibilika kakhulu wamanzi, yi-inorganic chemical compound enye yeekhemikhali ezinobungozi ezisetyenziswa kwibhubhoratri.Ba(OH)2.8H2Oyikristale engenambala kubushushu begumbi.Inobunzima be-2.18g / cm3, i-soluble yamanzi kunye ne-asidi, inetyhefu, inokubangela umonakalo kwi-nervous system kunye nenkqubo yokugaya.Ba(OH)2.8H2Oinomhlwa, inokubangela ukutshisa kwamehlo kunye nolusu.Inokubangela ukucaphuka komjelo wokwetyisa ukuba iginyiwe.Iimpendulo zomzekelo: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
