Chemical stability
no data available
Possibility of hazardous reactions
The solution in water is a strong base. It reacts violently with acid and is corrosive. Decomposes on heating. This produces sulfur oxides. Decomposes on contact with water. This produces highly toxic and flammable hydrogen sulfide (see ICSC 0165). Attacks metal. Reacts with strong oxidants. This produces sulfur oxides.

Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
