One of the tungstates. Common name for dodecatungstate M I 10 [W 12 O 46 H 10 ]・ n H 2 O (12WO 3 ・5M I 2 O・ n H 2 O). It is the most easily obtained of the polytungstates, and most of the tungstates normally referred to as tungstates in analytical reagents are of this type. There exists the isopolytungstate ion [W 12 O 46 H 10 ] 10- , a polynuclear complex with octahedral WO 6 units that share edges, as shown in the figure.
