Storage conditions
1. It should be stored in a cool and dry warehouse. The packaging should be sealed to prevent air oxidation.

2. Pay attention to moisture prevention. During transportation, it should be protected from rain and direct sunlight. It is strictly prohibited to store and transport together with acids, oxidants, and toxic and harmful substances.

When a fire breaks out, water and various fire extinguishers can be used to extinguish it.

Stability
1. It is easy to decompose when exposed to moisture and oxidizes into sodium sulfate when exposed to air. It is stimulating.

2. Contact with strong acids releases sulfur dioxide and generates corresponding salts. Heat to 150 ℃ for decomposition. A white powder with a strong SO2 odor, which loses SO2 in the air and absorbs O2 to transform into Na2SO4. Easy to dissolve in water, the aqueous solution is acidic. When the solution is heated above 65 ℃, it decomposes into Na2SO3 and SO2.
