Sodium molybdate CAS 7631-95-0
Sodium molybdate, formula Na2MoO4. Kulemera kwa molekyulu 205.92. Mwala wa diamondi woyera. Opaque white crystal. Malo osungunuka 687 ℃, kachulukidwe wachibale 3.2818. Sungunulani m'madzi. Dihydrate angapezeke mwa crystallization kuchokera amadzimadzi njira (zamchere njira ndi pH apamwamba kuposa 8). Chotsatiracho ndi kristalo woyera wa rhombohedral. MoO42- ma ion alipo ngati ma tetrahedron okhazikika okhala ndi kachulukidwe kakang'ono ka 3.28. Mukatenthedwa mpaka 100 ℃, mamolekyu a 2 amadzi amatayika kuti apeze zinthu zopanda madzi, zosungunuka mosavuta m'madzi, zimasungunuka m'magawo 1.7 amadzi ozizira komanso pafupifupi magawo 0,9 amadzi otentha. 5% yankho lamadzi pa 25 ℃ pH 9.0 ~ 10.0, osasungunuka mu ethyl acetate. Mwa pang'onopang'ono kuwonjezera asidi ndi sodium molybdate njira ndi kuchepetsa pH ya yankho, molybdate akhoza polymerized mu zosiyanasiyana mchere polymolybdate, kuphatikizapo sodium dimolybdate, sodium trimolybdate, paramolybdate sodium, sodium octamolybdate ndi sodium decamolybdate.
