Sodium Hydrosulfite Density

The density of sodium hydrosulfite, also known as sodium dithionite, is 1.4 g/cm³ at room temperature and standard atmospheric pressure. This value may vary slightly depending on the purity and temperature of the substance being measured. Sodium hydrosulfite is a white to off-white crystalline powder that is highly soluble in water, with a solubility of approximately 550 g/L at 20°C. It has a molecular weight of 174.11 g/mol and a chemical formula of Na2S2O4. The compound is commonly used as a reducing agent in various industrial processes, including textile and paper manufacturing, mineral ore flotation, and water treatment.
