Sodium molybdate CAS 7631-95-0 ke eng?

Sodium molybdate, foromo Na2MoO4. Boima ba molek'hule 205.92. Khalase e tšoeu ea taemane. Khalase e tšoeu e opaque. Sebaka se qhibilihang ke 687 ℃, letsoalo le amanang le 3.2818. Qhibiliha ka metsing. Dihydrate e ka fumanoa ka crystallization ho tloha tharollo ea aqueous (tharollo ea alkaline e nang le pH e phahameng ho feta 8). Ea ho qetela ke kristale e tšoeu ea rhombohedral. Li-MoO42- ion li teng e le li-tetrahedron tse tloaelehileng tse nang le tekano e lekanyelitsoeng ea 3.28. Ha mocheso o fihla ho 100 ℃, limolek'hule tse peli tsa metsi lia lahleha ho fumana ntho ea anhydrous, e qhibilihang habonolo metsing, e qhibilihang ka likarolo tse 1.7 tsa metsi a batang le likarolo tse ka bang 0.9 tsa metsi a belang. 5% tharollo ea metsi ka 25 ℃ pH 9.0 ~ 10.0, e ke keng ea qhibiliha ka ethyl acetate. Ka ho eketsa butle-butle acid ho sodium molybdate tharollo le ho fokotsa pH ea tharollo, molybdate e ka etsoa polymerized ka mefuta e fapaneng ea letsoai la polymolybdate, ho akarelletsa le sodium dimolybdate, sodium trimolybdate, sodium paramolybdate, sodium octamolybdate le sodium decamolybdate.
