Yellow Tungsten Oxide Solubleness

To determine whether the metal oxide dissolved in water or not, we can follow the method: except alkali metal elements (sodium, potassium, rubidium, cesium), the other metal oxides are insoluble in water. So yellow tungsten oxide is also insoluble in water, and the solubility in water is almost 0. Yellow tungsten oxide can react with alkali to form the corresponding soluble tungstate, so yellow tungsten oxide can be soluble in alkali.

In a certain temperature, the solubility of a solid substance in the 100g solvent to reach saturation state is the quality of the dissolved. Dissolubility refers to the extent to which a substance can be dissolved.
