Barium Hydroxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%

Fa'amatalaga Puupuu:

Barium hydroxide, o se vailaʻau vailaʻau faʻatasi ma le fua faʻasolosoloBa(OH)2, o se mea mautu paʻepaʻe, solu i le vai, o le vaifofo e taʻua o le vai barite, malosi alkaline. Barium Hydroxide ei ai se isi igoa, e taʻua: caustic barite, barium hydrate. O le monohydrate (x = 1), ua ta'ua o le baryta po'o le baryta-water, o se tasi lea o fa'alapotopotoga autu o le barium. O lenei monohydrate pa'epa'e pa'epa'e o le faiga fa'apisinisi masani.Barium Hydroxide Octahydrate, e pei o se puna tioata Barium tioata e le mafai ona faʻaaogaina, o se vailaʻau vailaʻau faʻapitoa lea o se tasi o vailaʻau sili ona mataʻutia o loʻo faʻaaogaina i totonu o fale suʻesuʻe.Ba(OH)2.8H2Oose tioata e le lanu i le vevela o le potu. O loʻo i ai le mamafa o le 2.18g / cm3, vai solu ma acid, oona, e mafai ona faʻaleagaina ai le tino ma le faʻaogaina o meaʻai.Ba(OH)2.8H2Oe pala, e ono mu ai mata ma pa'u. E ono fa'aoso ai le fa'afefe o le mea'ai pe a foloina. Fa'ata'ita'iga Tali: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
