What Are The Properties Of Sodium Tungstate?
Sodium tungstate is an inorganic compound with the chemical formula Na2WO4, which is also known as sodium wolframate. It is usually obtained as a white solid, which is soluble in water and exhibits a moderate level of hygroscopicity.
Some of the important properties of sodium tungstate are listed below:
1. Melting and Boiling Point: The melting point of sodium tungstate is 1,465°C (2,669°F), and it does not have a boiling point at atmospheric pressure due to its decomposition before reaching the boiling point.
2. Density: The density of sodium tungstate is 5.9 g/cm³, which is relatively high compared to other inorganic compounds.
3. Solubility: Sodium tungstate is highly soluble in water, with a solubility of approximately 78 g/100 mL at room temperature. It is also slightly soluble in ethanol.
4. pH: When dissolved in water, sodium tungstate solutions exhibit a slightly alkaline pH, typically around 8-9.
5. Stability: Sodium tungstate is stable under normal conditions but decomposes when exposed to strong acids or reducing agents.
6. Uses: Sodium tungstate is widely used in various industrial applications, including the production of tungsten metal and alloys, as a catalyst in organic synthesis, and as a reagent in analytical chemistry.
Overall, sodium tungstate is a versatile inorganic compound with unique properties that make it useful in a variety of applications.
