Ammonium metatungstate solubility refers to the maximum amount of ammonium metatungstate dissolved in a given solvent at a given temperature and pressure when the solvent is saturated. Below is the detailed information about the solubility of Ammonium Metatungstate:
Basic Properties of Ammonium Metatungstate
Ammonium metatungstate is an inorganic compound that usually exhibits white or yellowish crystals. It is soluble in water and also in ethanol. The solubility of ammonium metatungstate is usually considered to be relatively low, but can vary under different conditions.
Ammonium metatungstate solubility range
At room temperature, the solubility of ammonium metatungstate in water is approximately 2.8g/100mL of water.
Solubility is usually expressed as the number of grams of solute dissolved in 100mL of solvent, but in practice, this value may vary according to specific conditions.
Factors affecting solubility of ammonium metatungstate
Temperature
Temperature is an important factor affecting the solubility of ammonium metatungstate. Generally, the solubility of ammonium metatungstate increases as the temperature rises. This is because an increase in temperature intensifies the thermal movement of solvent molecules and increases the intermolecular distance, thus promoting the dissolution of solutes.
pH
The pH of the solution also affects the solubility of ammonium metatungstate. In a weakly acidic environment, the solubility of ammonium metatungstate is higher; while in a weakly basic environment, its solubility is lower.
Solvent
Different solvents also have influence on the solubility of ammonium metatungstate. For example, ammonium metatungstate is more soluble in water than in ethanol.
Ionic Strength
Ionic strength is also a factor that affects the solubility of ammonium metatungstate hydrate. The solubility of ammonium metatungstate hydrate is lower in solutions with high ionic strength, while its solubility is higher in solutions with low ionic strength.
Application of Ammonium Metatungstate Solubility
The solubility properties of ammonium metatungstate have applications in a variety of fields, including catalyst preparation, electronic materials manufacturing, metallurgy and ceramics industries. By controlling the solubility and related conditions, the application and optimization of ammonium metatungstate in specific fields can be achieved.
Therefore, the solubility of ammonium metatungstate is a parameter affected by many factors, and its value and application scenarios need to be considered on a case-by-case basis.
