Реакции воздуха и воды

Water soluble. Mixing with limited quantities of water can cause heating and decomposition with release of irritating gaseous sulfur dioxide.

Профиль реактивности

A strong reducing agent. Inorganic reducing agents, such as ZINC HYDROSULFITE, react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. Their reactions with oxidizing agents may be violent. Sulfites and hydrosulfites (dithionites) can react explosively with strong oxidizing agents. Sulfites generate gaseous sulfur dioxide in contact with oxidizing acids and nonoxidizing acids.

Угроза здоровью

INHALATION: Irritation of nose and throat. EYES: Mild irritant. SKIN: Irritant. INGESTION: Nausea and vomiting.

Пожароопасность

Special Hazards of Combustion Products: Decomposes giving off irritating SO 2

Профиль безопасности
