The physical state of ammonium metatungstate can be clearly indicated and summarized as follows:
Color
Ammonium metatungstate usually appears as a white crystalline powder or a slight yellow color. This color may be slightly different due to its purity, preparation conditions or storage method.
Solubility
Ammonium metatungstate is soluble in water and in ethanol, but insoluble in benzene. This solubility characteristic makes Ammonium Metatungstate have a wide range of applications in several industrial fields.
Melting point
Ammonium metatungstate has a melting point of 100ºC (dec.) (lit.). This means that at this temperature, ammonium metatungstate begins to change from a solid to a liquid.
Boiling point
The boiling point of ammonium metatungstate is about 200°C at standard atmospheric pressure (1 atm). This means that when this temperature is reached, ammonium metatungstate will begin to change from a liquid to a gas.
Density
Ammonium metatungstate has a density of about 3.13 g/cm3. This value reflects its mass per unit volume and is one of the most important parameters for describing the physical properties of a substance.
In summary, ammonium metatungstate is a white or slightly yellow crystalline powder with good water solubility and a specific melting and boiling point. These physical properties make ammonium metatungstate widely used in many industrial fields.
