Yonuvchan:Sodium dithionite is a first-class flammable item when wet according to national standards. It will react violently when it comes into contact with water, producing flammable gases such as hydrogen sulfide and sulfur dioxide, and releasing a large amount of heat. The reaction equation is: 2Na2S2O4+2H2O+O2=4NaHSO3, and the products further react to produce hydrogen sulfide and sulfur dioxide. Natriy ditioniti oltingugurtning oraliq holati va uning kimyoviy xususiyatlari beqaror. Bu kuchli kamaytirish xususiyatlarini ko'rsatadi. When it encounters strong oxidizing acids, such as sulfuric acid, perchloric acid, nitric acid, phosphoric acid and other strong acids, the two will undergo a redox reaction, and the reaction is violent, releasing a large amount of heat and toxic substances. Uning reaktsiya tenglamasi: 2na2s2o4 + 4hcl = 2hc2s2o4 + 4nacl

Sodium dithionite has a spontaneous combustion point of 250℃. Due to its low ignition point, it is a first-class flammable solid (the ignition point is generally below 300℃, and the flash point of low melting point is below 100℃). Issiqlik, yong'in, ishqalanish va ta'sirga duchor bo'lganda kuyish juda oson. Yuvish tezligi tez va yong'in xavfi yuqori. Yuvish jarayonida ishlab chiqarilgan gaz vodorod sulfididagi gaz yanada kattalashishga olib kelishi mumkin, uning yong'in xavfini oshirishi mumkin.

Sodium dithionite is a light yellow powdery substance. Kukun moddasi havodagi portlash aralashmasini hosil qilish oson. Dust explosion occurs when encountering a fire source. Natriy ditionit va eng muhim oksidlanish aralashmasi, masalan, xlorlar, nitratlar, perikratura yoki permaniyaliklar, portlovchi hisoblanadi. Even in the presence of water, it explodes after a slight friction or impact, especially after thermal decomposition, the flammable gas generated after the reaction reaches the explosion limit, then its explosion hazard is greater.
