What Is The Solubility Of Sodium Dithionite In Water?

Sodium dithionite is a water-soluble compound with a solubility of approximately 680 g/L at room temperature (25°C). The solubility may vary slightly depending on the temperature and pressure conditions. Sodium dithionite is highly soluble in water due to its polar nature and ability to form hydrogen bonds with water molecules. When sodium dithionite dissolves in water, it dissociates into Na+ and the dithionite anion (S2O4²-) ions, which are stabilized by hydration shells formed by water molecules.
