Sodium nitrite (NaNO2) bụ nnu inorganic nke ion nitrite na mmeghachi omume ion sodium na-emepụta.Sodium nitrite na-adị mfe hydrolyzing na soluble na mmiri na mmiri mmiri amonia.Mmiri mmiri ya bụ alkaline, PH bụ ihe dịka 9;na ọ bụ ntakịrị soluble na organic mgbaze dị ka ethanol, methanol na ether.Ọ bụ oxidizer siri ike ma nwee ihe na-ebelata ya.Mgbe ekpughere ya na ikuku, Sodium Nitrite ga-eji nwayọọ nwayọọ mee oxidized, wee ghọọ sodium nitrate n'elu.A na-ahapụ gas nitrogen dioxide Brown n'okpuru ọnọdụ acid na-adịghị ike.Ịkpọtụrụ ihe ndị na-emepụta ihe ma ọ bụ ndị na-ebelata ihe ga-eduga na mgbawa ma ọ bụ combustion, Ọzọkwa, na-ahapụ nitrogen oxide gas na-egbu egbu ma na-akpasu iwe.Sodium nitrite nwekwara ike oxidized site na ike oxidizing agents, karịsịa ammonium nnu, dị ka ammonium nitrate, ammonium persulfate, wdg, nke nwere ike na-emekọ ihe ọnụ na-emepụta elu okpomọkụ na nkịtị okpomọkụ, na-eduga na combustible ihe ọkụ.Ọ bụrụ na ọ dị ọkụ ruo 320 ℃ ma ọ bụ n'elu, Sodium Nitrite ga-aghọ oxygen, nitrogen oxide na sodium oxide.Mgbe ị na-akpọtụrụ na ihe ndị dị ndụ, ọ dị mfe ọkụ na ịgbawa.
