Sodium Nitrite
ʻO ka sodium nitrite
| Waiwai | |
| ʻO ke kumu hoʻohālike | NaNO3 |
| Molar mass | 84.9947 g/mol |
| Ka nana aku | Pauda keʻokeʻo |
| ʻO ka mānoanoa | 2.257 g/cm3, paʻa |
| Lae hehee | 308 °C (586 °F; 581 K) |
| Lae paila | 380 °C (716 °F; 653 K) pohō |
| Solubility i ka wai | 73 g/100 mL (0 °C) 91.2 g/100 mL (25 °C) 180 g/100 mL (100 °C) |
| Ka hoʻoheheʻe | hiki ke hoʻoheheʻe ʻia i loko o ka amonia, hydrazine hiki ke hoʻoheheʻe i ka waiʻona hiki ke hoʻoheheʻe iki i ka pyridine hiki ʻole ke hoʻoheheʻe ʻia i ka acetone |
ʻO ka sodium nitrite (NaNO2) he paʻakai anorganic i hana ʻia e nā ion nitrite a me ka hopena o ka sodium.ʻO ka sodium nitrite he maʻalahi ka hydrolyzing a hoʻoheheʻe ʻia i ka wai a me ka ammonia wai.He alkaline kona wai wai, ʻo ka PH ma kahi o 9;a hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethanol, methanol a me ka etera.He oxidizer ikaika a he waiwai hoʻemi hoʻi.Ke hōʻike ʻia i ka lewa, e hoʻoneʻe ʻia ka Sodium Nitrite, a lilo i sodium nitrate ma ka ʻili.Hoʻokuʻu ʻia ke kinoea nitrogen dioxide ʻeleʻele ma lalo o ke kūlana ʻakika nāwaliwali.ʻO ka hoʻopili ʻana me ka mea ola a i ʻole ka mea hoʻohaʻahaʻa e alakaʻi i ka pahū a i ʻole ka puhi ʻana, a me ka hoʻokuʻu ʻana i nā mea ʻawaʻawa a me ka hoʻonāukiuki ʻana i ke kinoea nitrogen oxide.Hiki ke hoʻoheheʻe ʻia ka sodium Nitrite e nā mea oxidizing ikaika, ʻoi aku ka paʻakai ammonium, e like me ka ammonium nitrate, ammonium persulfate, a me nā mea ʻē aʻe, hiki ke launa pū kekahi me kekahi e hana i ka wela kiʻekiʻe i ka mahana maʻamau, e alakaʻi ana i nā mea puhi ahi e puhi.Inā wela i ka 320 ℃ a i ʻole, e hoʻoheheʻe ʻia ka Sodium Nitrite i ka oxygen, nitrogen oxide a me ka sodium oxide.Ke hoʻopili ʻia me ka mea organik, maʻalahi ke puhi a pahū.
Nā noi:
ʻIkepili Chromatographic: Hoʻohana ʻia ka loiloi Drip e hoʻoholo i ka mercury, potassium a me ka chlorate.
Diazotization reagents: Nitrosation reagent;Ka nānā ʻana i ka lepo;ʻO ka hoʻoholo ʻana o ka bilirubin serum i ka hoʻāʻo ʻana i ka hana o ka ate.
Mea hoʻomaʻemaʻe no ke kilika a me ke olonā, mea hoʻomaʻamaʻa wela metala;mea hoʻopaʻa hoʻopale kila;Cyanide poisoning antidote, laboratory analytical reagents.Ma ka wahi meaʻai, hoʻohana ʻia ia e like me nā mea chromophores 'i ka wā e hana ai i nā huahana ʻiʻo, a me nā antimicrobial agents, preservatives.Loaʻa iā ia nā noi i ka bleaching, electroplating a me ka mālama metala.
Ka mālama ʻana: pono e mālama ʻia ka sodium nitrite i kahi haʻahaʻa haʻahaʻa, maloʻo a me ka hale kūʻai ventilated.Paʻa nā puka a me nā puka makani e pale aku i ka lā.Hiki ke mālama ʻia i loko o ka waihona me nā nitrates ʻē aʻe ma waho o ka ammonium nitrate, akā hoʻokaʻawale ʻia mai nā mea organik, nā mea inflammable, ka mea hoʻemi a me ke kumu ahi.
