Sodium molybdate CAS 7631-95-0
Sodium molybdate, formula Na2MoO4. Uburemere bwa molekuline 205.92. Diyama yera. Ibara ryera ryera. Gushonga ingingo 687 ℃, ubucucike bugereranije 3.2818. Shonga mumazi. Dihydrate irashobora kuboneka mugutandukanya ibintu biva mumazi (igisubizo cya alkaline hamwe na pH irenze 8). Iheruka ni rhombohedral yera. MoO42- ion ibaho nka tetrahedron isanzwe ifite ubucucike bwa 3.28. Iyo ashyutswe kugeza kuri 100 molecules, molekile 2 zamazi zabuze kugirango zibone ibintu bidafite amazi, bigashonga byoroshye mumazi, bigashonga mubice 1.7 amazi akonje nibice 0.9 byamazi abira. 5% yumuti wamazi kuri 25 ℃ pH 9.0 ~ 10.0, udashonga muri Ethyl acetate. Mugushiramo buhoro buhoro aside ya sodium molybdate no kugabanya pH yumuti, molybdate irashobora guhindurwamo polymer mumyunyu itandukanye ya polymolybdate, harimo sodium dimolybdate, sodium trimolybdate, sodium paramolybdate, sodium octamolybdate na sodium decamolybdate.
