Appearance:Zinc dithionite is a white powder. It is noncombustible. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. It is used to bleach wood pulp, textiles, and other naturally occurring materials.
Water Solubility:28.00 lb/100 lb water at 68 deg F
Flammability characteristics:Prone to spontaneous combustion; flammable in case of heat and open flame; emit toxic sulfur dioxide gas in case of water, acid and oxidant
Odor:Slight sulfur dioxide odor
Experimental Properties:Solubility: 40 g/100 g water at 20 °C; MP: 200 °C (decomp) /Zinc hydrosulfite dihydrate/
Air and Water Reactions:Mixing with limited quantities of water can cause heating and decomposition with release of irritating gaseous sulfur dioxide. This hazard is reduced by dilution with large quantities of water. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Sulfur Dioxide gas will be created in 6.9 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.
Reactive Group:Anhydrides
Reactivity Alerts:Strong Reducing Agent
Reactivity Profile:Undergoes a self-accelerating hydrolysis reaction upon contact with water, producing thiosulfate and bisulfite compounds and heat in neutral or acidic aqueous solution. Reacts with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. These reactions may be violent.
