Sodium molybdate CAS 7631-95-0
Sodium molybdate, formula Na2MoO4. Miisaanka molecular 205.92. crystal dheeman cad. crystal cad oo aan muuqan. barta dhalaalka 687 ℃, cufnaanta qaraabada 3.2818. Ku milmi biyaha. Biyo-baxa waxaa lagu heli karaa crystallization laga bilaabo xal aqueous (xalka alkaline leh pH ka sarreeya 8). Ka dambe waa crystal rhombohedral cad. MoO42-ions waxay u jiraan sida tetrahedrons caadiga ah oo leh cufnaanta qaraabada ah 3.28. Marka la kululeeyo ilaa 100 ℃, 2 molecules oo biyo ah ayaa lumaya si ay u helaan walxo anhydrous ah, si fudud ugu milmaya biyaha, ku milma 1.7 qaybood oo biyo qabow ah iyo qiyaastii 0.9 qaybood oo biyo ah oo karkaraya. 5% xal aqueous at 25 ℃ pH 9.0 ~ 10.0, aan milmin in ethyl acetate. Iyada oo si tartiib tartiib ah loogu daro aashitada xalka sodium molybdate iyo yaraynta pH ee xalka, molybdate waxaa lagu polymerized karaa noocyo kala duwan oo cusbada polymolybdate, oo ay ku jiraan sodium dimolybdate, sodium trimolybdate, sodium paramolybdate, sodium octamolybdate iyo sodium decamolybdate.
