Fluoroxytungstates are inorganic compounds of the metal of tungsten , obtained by the reaction of hydrofluoric acid with tungstates. Most of them under normal conditions are white or colorless crystalline substances that dissolve well in water . Eat the glass .

Properties
Fluoroxytungstates are divided into 3 groups: Me [WO 2 F 3 ], where Me = alkali metal ions , thallium, ammonium, Me [WO 2 F 3 ] 2 , Me = zinc , cadmium , manganese and magnesium ions ; Me [WO 2 F 4 ] (Me = potassium, thallium and ammonium ions); Me 3 [WO 3 F 3 ], where Me = ammonium ions and alkali metals.
In the last group, the substances are very similar in their properties, and form colorless crystals of the cubic syngony , decompose in water.
