Sodium cyanide he mea hoʻohui i loaʻa nā noi ʻoihana ʻelua a me nā hopena palekana koʻikoʻi ma muli o kona ʻona kiʻekiʻe. Ma kēia ʻatikala, e pane mākou i nā nīnau maʻamau e pili ana i kāna haʻilula kemika a kaupū paona.
He aha ke ʻano kumu hoʻohālike o ka Sodium Cyanide?
ʻO ke ʻano kemika o ka sodium cyanide is NaCN. Loaʻa kēia ʻano kumu mai ka hui ʻana o ka sodium (Na⁺) a me ka cyanide ion (CN⁻). Hāʻawi koke ʻo Sodium, he metala alkali, i hoʻokahi electron no ka hoʻokō ʻana i kahi hoʻonohonoho electron paʻa, e hana ana i kahi ion i hoʻoili maikaʻi ʻia. ʻO ka cyanide ion, ma ka ʻaoʻao ʻē aʻe, he ʻekolu ʻātoma kalapona - i hoʻopaʻa ʻia i kahi ʻātoma nitrogen a lawe i kahi hoʻopiʻi ʻino. Ke hui pū ʻia nā ion sodium a me ka cyanide, hana lākou i pūhui ionic, ʻO ka sodium Cyanide, me ke kumu NaCN.
Pehea e helu ʻia ai ke kaumaha o ka Sodium Cyanide?
No ka helu ʻana i ke kaumaha molecular (ʻike pū ʻia ʻo molar mass) o ʻO Sodium cyanide, pono mākou e noʻonoʻo i nā paona atomika o nā mea i hoʻohui ʻia.
ʻO ke kaumaha atomika o ka sodium (Na) ma kahi o 22.99 g/mol.
ʻO ke kaumaha o ke kalapona (C) ma kahi o 12.01 g/mol.
Aia ma kahi o 14.01 g/mol ke kaumaha atomika o ka nitrogen (N).
No ka sodium cyanide (NaCN), no ka mea, aia hoʻokahi ʻātoma sodium, hoʻokahi ʻātoma kalapona, a hoʻokahi ʻātoma nitrogen i kēlā me kēia ʻāpana kumu, ua helu ʻia ke kaumaha molekala penei:
Kaumaha molekalale o NaCN = (Ke kaumaha ʻĀtoma o Na) + (Ke kaumaha ʻĀtoma o C) + (Ke kaumaha ʻĀtoma o N)
= 22.99 g/mol + 12.01 g/mol + 14.01 g/mol
= 49.01 g/mol
No laila, ua like ke kaumaha o ka sodium cyanide 49.01 g / mole.
Hoʻohana nui ʻia ʻo Sodium cyanide, me kāna ʻano kemika kikoʻī a me ke kaumaha molekala, i nā ʻoihana like ʻole, e like me ka ʻeli gula no ka unuhi ʻana i ke gula mai kāna mau ores ma o ke kaʻina i kapa ʻia ʻo cyanidation. Eia nō naʻe, ma muli o kona ʻona koʻikoʻi, pono ka mālama pono ʻana a me nā protocol palekana koʻikoʻi i ka wā e pili ana i kēia pūhui. He mea koʻikoʻi ka hoʻomaopopo ʻana i kāna mau waiwai kemika, me ke kumu a me ke kaumaha molekala no nā noi ʻoihana a me ka hoʻokele palekana.
