Barium Acetate 99.5% Cas 543-80-6
Barium acetate ndi mchere wa barium (II) ndi acetic acid wokhala ndi mankhwala a Ba (C2H3O2)2.Ndi ufa woyera umene umasungunuka kwambiri m'madzi, ndipo umawola ku Barium oxide pa kutentha.Barium acetate ili ndi gawo ngati mordant komanso chothandizira.Ma Acetates ndi otsogola abwino kwambiri popanga zinthu zodziwikiratu kwambiri, zothandizira, ndi zida za nanoscale.

Barium Hydrooxide (Barium Dihydroxide) Ba(OH)2∙ 8H2O 99%
Barium hydroxide, mankhwala opangidwa ndi mankhwalaBa(OH) 2, ndi chinthu cholimba choyera, chosungunuka m'madzi, yankho lake limatchedwa madzi a barite, alkaline amphamvu.Barium Hydroxide ili ndi dzina lina, lomwe ndi: caustic barite, barium hydrate.The monohydrate (x = 1), yotchedwa baryta kapena baryta-madzi, ndi imodzi mwazinthu zazikulu za barium.Izi woyera granular monohydrate ndi mwachizolowezi malonda mawonekedwe.Barium Hydrooxide Octahydrate, monga gwero la madzi osasungunuka a crystalline Barium, ndi mankhwala osokoneza bongo omwe ndi amodzi mwa mankhwala oopsa kwambiri omwe amagwiritsidwa ntchito mu labotale.Ba(OH)2.8H2Ondi kristalo wopanda mtundu pa kutentha kwa chipinda.Ali ndi kachulukidwe ka 2.18g / cm3, osungunuka m'madzi ndi asidi, owopsa, amatha kuwononga dongosolo lamanjenje ndi m'mimba.Ba(OH)2.8H2Ondi zowononga, zingayambitse kuyatsa kwa diso ndi khungu.Zingayambitse kukwiya kwa m'mimba ngati zitamezedwa.Zitsanzo Zanu: • Ba(OH)2.8H2O + 2NH4SCN = Ba(SCN)2 + 10H2O + 2NH3
