Nkọwa ngwaahịa:
(1) sodium nitrite nkịtị: kristal dị mma na-acha ọcha, ma ọ bụ odo odo.
(2) sodium nitrite ntụ ntụ: kristal ọcha, enweghị lumps, rụrụ arụ.Nnukwu ike ndọda 2.168, enweghị isi, nnu dị ntakịrị, na-atọ ụtọ nke ukwuu, na-agbaze ngwa ngwa na mmiri, ebe agbaze nke 271°C, ire ere okpomọkụ nke 320°C, oxidative na reductive.Eji nwayọọ nwayọọ na-abanye oxygen n'ime sodium nitrate na ikuku, dị mfe ịmepụta ogige nitrogen na amino dị iche iche na obere okpomọkụ.
(3) Nri ọkwa Sodium Nitrite bụ ọcha ma ọ bụ ubé odo rhombohedral crystal ma ọ bụ ntụ ntụ, molecular usoro NaNo2, agbaze ebe 271 ° C, ubé nnu, mfe deliquesce, soluble na mmiri, aqueous ngwọta bụ alkaline, na ikuku nwere ike iji nwayọọ nwayọọ. oxidized n'ime sodium nitrate.
