- No ke aha e hana ai ka hoʻoheheʻe calcium chloride i ka uila?
- No ke aha i hoʻokō nui ai ka sodium chloride (NaCl)?
- No ke aha i ʻoi aku ai ka uila o ka calcium chloride (CaCl) ma mua o ka sodium chloride (NaCl)?
- ʻO ka sodium chloride me ka calcium chloride
- Nīnau pinepineʻia
- No ke aha i hoʻoheheʻe ai ka sodium chloride i ka uila?
- Makemake ʻia ka calcium chloride a i ʻole ka sodium chloride no ka hoʻoheheʻe ʻana i ka hau?
- He hygroscopic maoli anei ka calcium chloride?
- He aha nā mea e pili ana i ka solubility? E noʻonoʻo i kēia nīnau: Ua ʻoi aku ka maʻemaʻe o ka calcium chloride ma mua o ka barium chloride?
Hiki i ka calcium chloride ke hana i ka uila? Ma kēia ʻatikala, e kōkua wau iā ʻoe e ʻike i ka pane.
Ua kamaʻāina mākou i ka sodium chloride a i ʻole ka paʻakai papa, akā ʻaʻole me ka calcium chloride. ʻO ka calcium chloride a me ka sodium chloride he mau chloride metala. Eia nō naʻe, ʻokoʻa nā hiʻohiʻona kemika o ka calcium a me ka sodium (a i ʻole kekahi metala chloride ʻē aʻe), hiki ke huikau. He mea koʻikoʻi ka kemika o nā metala chlorides i ka hoʻomaopopo ʻana i ka hana ʻana o nā ion i ka uila.
Ma keʻano laulā, i ka wā e hoʻoheheʻe ai ka paʻakai, ʻo kona mau iona i hoʻokaʻawale ʻia (nā mea pono e hoʻokumu i ka paʻakai-calcium a me nā ion chloride, i kā mākou hihia) hiki ke neʻe i loko o ka hopena, e hiki ai ke kahe ka uku. No ka mea, loaʻa nā ion, e hoʻokele ka hopena i ka uila.
E nānā ma lalo no nā kikoʻī hou aku.
He mea lawe uila maikaʻi anei ka calcium chloride?
ʻO ka calcium chloride ma ke ʻano hoʻoheheʻe he mea hoʻokele uila maikaʻi. ʻO ka calcium chloride kahi mea hoʻokele maikaʻi ʻole o ka wela. Ka helu hoʻolapalapa 1935°C. He hygroscopic a hoʻopaʻa i ka makū mai ka lewa.
No ke aha e hana ai ka hoʻoheheʻe calcium chloride i ka uila?
Loaʻa i nā hāʻina calcium chloride nā ion mobile e hoʻololi i ka uku a i ʻole ka uila.
Ke hoʻoheheʻe ʻia ka paʻakai, ʻokoʻa ka neʻe ʻana o kona mau iona i hoʻokaʻawale ʻia (nā mea i hana ʻia i ka paʻakai—calcium a me nā ion chloride, i loko o kā mākou hihia) e neʻe a puni i ka hāʻina, e hiki ai ke kahe ka uku. No ka mea, loaʻa nā ion, e hoʻokele ka hopena i ka uila.
Calcium chloride, paʻa; hopena maikaʻi ʻole.
ʻO ka hoʻonā calcium chloride; hopena maikaʻi
No ke aha i hoʻokō nui ai ka sodium chloride (NaCl)?
Hoʻoheheʻe ka wai a me nā mea polar ʻē aʻe i ka NaCl. Hoʻopuni nā molekala wai i kēlā me kēia cation (ka uku maikaʻi) a me ka anion (ka uku ʻino). Hoʻopili ʻia kēlā me kēia ion e ʻeono mau mole wai.
ʻO nā pūhui Ionic i loko o ke kūlana paʻa, e like me NaCl, ua hoʻopaʻa ʻia ko lākou mau ion i kahi kūlana a no laila ʻaʻole hiki ke neʻe. No laila, ʻaʻole hiki i nā pūhui ionic paʻa ke alakaʻi i ka uila. ʻO nā iona i loko o nā pūhui ionic he moʻo a manuahi paha ke kahe ʻana ke hoʻoheheʻe ʻia, no laila hiki i ka NaCl hoʻoheheʻe ke alakaʻi i ka uila.
No ke aha i ʻoi aku ai ka uila o ka calcium chloride (CaCl) ma mua o ka sodium chloride (NaCl)?
ʻOi aku ka nui o nā iona (3) ma mua o ka sodium chloride (2).
No ka mea, he elua ion o ka NaCl a he ekolu ko CaCl2. ʻO CaCl ka mea nui loa a no laila ʻoi aku ka kiʻekiʻe o ka conductivity. ʻO NaCl ka mea liʻiliʻi loa (hoʻohālikelike ʻia me CaCl) a loaʻa iā ia ka haʻahaʻa haʻahaʻa haʻahaʻa.
ʻO ka sodium chloride me ka calcium chloride
I ka pōkole, ʻo nā pūhui paʻakai alkaline ka calcium chloride a me ka sodium chloride. Loaʻa i kēia mau pūhui ʻelua nā ion chloride, akā ma nā ʻāpana like ʻole. ʻO ka ʻokoʻa nui ma waena o ka paʻakai calcium chloride a me ka paʻakai sodium chloride ʻo ia ka mea i loaʻa i kēlā me kēia molekala calcium chloride ʻelua mau mole chlorine a ʻo kēlā me kēia mole sodium chloride he hoʻokahi.

No ke aha i hoʻoheheʻe ai ka sodium chloride i ka uila?
I loko o kahi hui ionic, e like me NaCl chloride, ʻaʻohe electrons manuahi. Hoʻopili nā mana electrostatic ikaika i nā electrons i loko o nā mea paʻa. No laila, ʻaʻole lawe ka sodium chloride i ka uila ma ke ʻano paʻa. No laila, ʻo ka loaʻa ʻana o nā ion mobile e hoʻoholo i ka conductivity o NaCl i ke kūlana hoʻoheheʻe.
Makemake ʻia ka calcium chloride a i ʻole ka sodium chloride no ka hoʻoheheʻe ʻana i ka hau?
Hiki i ka calcium chloride (CaCl) ke hoʻoheheʻe i ka hau ma -20°F, ʻoi aku ka haʻahaʻa ma mua o ka helu hoʻoheheʻe o kekahi huahana hoʻoheheʻe hau. Hehe wale ka NaCl a hiki i 20°F. A i ka hoʻoilo, ma ka hapa nui o nā mokuʻāina ʻākau o ʻAmelika Hui Pū ʻIa, hāʻule ka mahana ma lalo o 20°F.
He hygroscopic maoli anei ka calcium chloride?
ʻO ka calcium chloride anhydrous, a i ʻole calcium dichloride, he pūhui ionic calcium chloride. Loaʻa iā ia kahi kala keʻokeʻo paʻa crystalline i ka mahana ambient. (298 K). He hygroscopic no ka mea e hoʻoheheʻe maikaʻi i ka wai.
He aha nā mea e pili ana i ka solubility? E noʻonoʻo i kēia nīnau: Ua ʻoi aku ka maʻemaʻe o ka calcium chloride ma mua o ka barium chloride?
Hoʻoholo ʻia ka conductivity e ka neʻe ʻana o nā ion, a ʻoi aku ka maʻamau o nā ion liʻiliʻi.
Ke ʻōlelo ʻia nā molekole wai, ʻo ia ka manaʻo o nā papa o ka hydration.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- Na Nitrogen ke alakai i ka uila
- ʻO ka waiʻona Isopropyl ke alakaʻi i ka uila
- Lawe ʻo Sucrose i ka uila
