Ammonium metatungstate solubility generally refers to AMT solubility in water, AMT has a good water solubility with the solubility of 303.99/100g under 20℃, and quite stable, also the solubility increased with increasing temperature.

Solubility is signed of S, the quality of a solid solute in 100g of solvent when achieved saturation at a certain temperature, which is the solubility of the substance in this solvent. Solubility of the substance belongs to physical property. Furthermore, in the Unspecified circumstances, it is generally it refers to the solubility in the water.

whether one substance is dissolved or not, and the dissolving ability depends on property (refer to solvent and solute) of the material itself on the one hand; on the other hand, it relates to the external conditions such as temperature, pressure, type of solvent and so on. In addition, the solubility is significantly affected by temperature, and the solubility of most solid material is increased with the temperature rising; while the solubility of gaseous substances is contrary, decreases with increasing of temperature.
