He aha nā ʻano kino o ka Sodium Cyanide?

Sodium Cyanide (NaCN) he pūhui kemika i huki nui ʻia ma muli o kona ʻona a me nā noi ʻoihana. Ka hoomaopopo ana i kona Nāʻano kino he mea koʻikoʻi no ka mālama ʻana, mālama ʻana, a me nā noʻonoʻo palekana. Eia na waiwai kino nui o ʻO Sodium cyanide:

1. Keʻano: Kaona cyanide ʻike pinepine ʻia e like me ke keʻokeʻo, nā granule crystalline, ka pauka, a i ʻole nā ​​puʻupuʻu. Ma kona ʻano maʻemaʻe, he ʻano maʻemaʻe, ʻaʻohe waihoʻoluʻu kona ʻano i ka wā e hoʻonā ai a i ʻole he aniani akaka. Eia nō naʻe, ʻike ʻia paha nā laʻana kalepa i kekahi manawa - keʻokeʻo ma muli o nā haumia.

2. Hoʻōkuhi: He ala ʻalemona kona, ʻano ʻano. Akā he mea nui e hoʻomaopopo ʻaʻole hiki i nā kānaka a pau ke ʻike i kēia ʻala. Hoʻoholo ʻia ka hiki ke honi i nā pūhui cyanide, me ka hapa nui o ka heluna kanaka hiki ʻole ke ʻike i ka ʻala. Eia kekahi, ma kahi maloʻo, ʻO ka sodium Cyanide ʻaʻohe ʻala pinepine. E ʻike hou ʻia ka ʻala ke ʻike ʻia i ka ea maʻa a i ʻole ka wai, a laila hydrolyzes e hoʻokuʻu i ka hydrogen cyanide (HCN), nona ka ʻala ʻalemona kaulana.

3. Lae hehee a me ka paila: He kiʻekiʻe ko ka sodium cyanide ma kahi o 563.7 °C (1046.7 °F). Hōʻike kēia i nā paʻa ionic ikaika i loko o ka pūhui. Ma kahi o 1496 °C (2725 °F) kona wahi paila. He ʻano maʻamau kēia mau mea hoʻoheheʻe a me ka paila kiʻekiʻe o nā pūhui ionic, kahi i loaʻa ai nā mana electrostatic ikaika o ka huki ʻana ma waena o nā cation sodium (Na⁺) a me nā anion cyanide (CN⁻).

4. nuʻa: Ka mānoanoa o ka sodium cyanide he 1.595 g/cm³. Kōkua kēia waiwai nui i ka hoʻoholo ʻana i ka nui o ka mea i loko o kahi leo i hāʻawi ʻia, he mea nui ia no nā noi ʻoihana a me nā kaʻina hana.

5. Palekana: Hiki ke hoʻoheheʻe ʻia ka sodium cyanide i ka wai. Ma 20 °C, ma kahi o 48 grams o ka sodium cyanide hiki ke hoʻoheheʻe i 100 milliliters o ka wai. Ke piʻi aʻe ka mahana, piʻi pū kona solubility. No ka laʻana, ma 34.7 °C, ma kahi o 82 grams hiki ke hoʻoheheʻe i 100 milliliters o ka wai. Hiki ke hoʻoheheʻe ʻia i loko o ka ethanol a hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe polar e like me ka amonia. I loko o ka wai, ua hoʻokaʻawale ʻia i loko o nā ion sodium (Na⁺) a me nā ion cyanide (CN⁻), nona ke kuleana no ka nui o kāna mau mea kemika a me nā mea ʻona.

6. ʻO Hygroscopicity: ʻO ka sodium cyanide he hygroscopic, ʻo ia hoʻi, he manaʻo kona e komo i ka makū mai ka lewa. Ke komo ia i ka wai, hiki iā ia ke hana i nā hydrates. I kekahi mau hihia, hiki i kēia ke alakaʻi i ka hoʻopaʻa ʻana a i ʻole ka hoʻopili ʻana o ka mea paʻa inā mālama ʻia ia i loko o kahi wahi haʻahaʻa. Loaʻa i kēia waiwai nā hopena no kāna mālama ʻana, no ka mea pono e mālama ʻia i kahi maloʻo e mālama i kona kūpaʻa a pale i nā hopena i makemake ʻole ʻia.

7. Papa Kuhikuhi Refractive: ʻO ka index refractive o ka sodium cyanide ma kahi o 1.452. ʻO ka index refractive he ana ia o ka nui o ka malamalama i piʻo ke hele i loko o kekahi mea. Hiki ke hoʻohana ʻia kēia waiwai i nā ʻano analytical no ka ʻike ʻana a me ke ʻano o ka sodium cyanide i kekahi mau kūlana, ʻoi aku ka nui o ka hui pū ʻana me nā waiwai kino a me nā mea kemika.

I ka hōʻuluʻulu manaʻo, pāʻani koʻikoʻi nā waiwai kino o ka sodium cyanide, e like me kona helehelena, ʻala, heheʻe a me ka paila ʻana, density, solubility, hygroscopicity, a me refractive index, i nā hana koʻikoʻi i kāna hoʻohana ʻana i ka ʻoihana a me nā kaʻina hana palekana. Hāʻawi ʻia i kona ʻawaʻawa nui, pono ka ʻike o kēia mau waiwai no ka poʻe e hana pū ana a puni kēia pūhui.
