Product Description


Sodium dithionite Cas No: 7775-14-6
 

Product Description

White crystalline powder with odor of sulfur dioxide. The relative density is about 1.3. Soluble in water, almost insoluble in ethanol. Unstable, easy to decompose by oxidation. Moisture, heat, or exposure to air can accelerate its decomposition and even combustion, producing sulfur dioxide and a lot of heat when it decomposes. Moisture or exposure to air will lose potency and may burn. Heating to 75 ~ 80ºC above decomposition, to 190ºC will explode.
