Sodium Dithionite Solubility

Sodium dithionite is a water-soluble compound with a solubility of approximately 550 g/L at room temperature (25°C). However, its solubility decreases as the temperature increases. At 50°C, the solubility drops to about 160 g/L, and at 100°C it is only around 45 g/L. Sodium dithionite is insoluble in organic solvents such as ethanol, ether, and benzene. It is also slightly soluble in methanol, with a solubility of about 20 g/L. The solubility of sodium dithionite in acidic solutions is lower than in neutral or alkaline solutions.
