Barium Hydroxide (Barium Dihydroxide) BA (OH) 2 × 8h2o 99%
Barium Hydroxide, chemapound yemakemikari nemakemikari mafomulaBa(Ah) 2, ine chena yakasimba, ine ruvara mumvura, mhinduro yacho inonzi barite mvura, yakasimba alkaline. Barium Hydroxide ine rimwe zita, kureva: caustic barite, atium hydrate. Monohydrate (x = 1), inozivikanwa seBaryta kana Baryta-Mvura, ndeimwe yemakomputa makuru eBariamu. Iyi chena granular monhydrate ndiyo yakajairwa yekutengeserana fomu.Barium Hydroxide OctHydrate, semvura yakanyanya kuchemera yekristine Bariamu, inzvimbo yemakemikari iyo ndiyo imwe yemakemikari ane ngozi anoshandiswa muurabhoritari.BA (OH) 2.8h2oIcho chisina ruvara crystal pamhepo tembiricha. Iyo ine density ye 2.18g / cm3, marara, mvura inokurumidza, ine muchetura, inogona kukonzera kukuvadza kune system yetsinga uye yekugaya system.BA (OH) 2.8h2oinokoshesa, inogona kukonzera kupisa uye ganda. Inogona kukonzera kugaya turakiti kutsoropodza uku kana kumedzwa. Muenzaniso Maitiro: • BA (OH) 2.8h2o + 2NH4SCN = BA (SCN) 2 + 10H2O + 2NH3
