Sodium Tungstate Dihydrate Solubility In Water

Sodium tungstate dihydrate is a compound with the chemical formula Na2WO4•2H2O. It is highly soluble in water, with a solubility of approximately 143 g/L at room temperature (25°C). The high solubility of this compound is due to its ionic nature, as it dissociates into sodium cations (Na+) and tungstate anions (WO42-) when dissolved in water. The presence of two water molecules in the formula also contributes to its solubility, as the water molecules can interact with the ions through hydrogen bonding. Overall, the solubility of sodium tungstate dihydrate in water is quite high, making it easily dissolve and readily available for use in various applications such as in the production of tungsten metal and ceramics.
