Hiki i ke kō ke alakaʻi i ka uila?
Nā mea
Ke noʻonoʻo ʻoe i kahi mea hiki ke hoʻokele i ka uila, ʻaʻole maʻamau ke kō ka mea mua i manaʻo ʻia, akā e kāhāhā paha ka ʻoiaʻiʻo iā ʻoe.
Hoʻohana ʻia ke kō i nā meaʻai he nui, me nā keke a me ke kokoleka. Hoʻokumu ia i ka hopena o ke kō i loko o ka wai a maʻalahi ka wehe. Akā ʻaʻole maopopo ka nui o ka poʻe i ka hoʻouna ʻana i ka uila a i ʻole ka hopena kō, ʻoiai ua ʻike mākou a pau e hana nā solution electrolyte, e like me ka wai wai o NaCl. Ma ke ʻano he loea uila me ka makemake i ka kemika, e uhi au i kēia kumuhana a me nā kumuhana pili i kēia alakaʻi.
ʻO ka hōʻuluʻulu pōkole: ʻAʻole hoʻokele uila ka hoʻonā kō. ʻAʻole i loaʻa nā ion manuahi e pono ai no ka lawe ʻana i ka uila i loko o ka hāʻina kō. Hoʻopaʻa pū ʻia nā molekole kō i nā paʻa Covalent, me ka pale ʻana iā lākou mai ka hoʻokaʻawale ʻana mai nā ion manuahi i ka wai. No ka mea, ʻaʻole ia e hoʻoheheʻe i nā ion manuahi e like me ka hoʻonā electrolyte, hana ke kō i ka insulator.
Ma lalo nei e hana au i ka nānā ʻana i ka hohonu.
Hiki i ke kō ke hoʻoili i ka uila?
ʻAʻole ka pane, ʻaʻole hoʻokele uila ka hoʻonā kō.
Ke kumu: ʻAʻole i loaʻa nā ion manuahi e pono ai no ka lawe ʻana i ka uila i loko o ka hāʻina kō. Hoʻopaʻa pū ʻia nā molekole kō i nā mea paʻa Covalent i ʻole e hoʻokaʻawale ʻia mai nā ion mobile i ka wai. He insulator ka solution kō no ka mea, ʻaʻole like me ka solution electrolyte, ʻaʻole ia e hoʻokaʻawale i nā ion manuahi.
Kemika o ka mole kō
Kumu: C12H22O11
ʻO 12 mau ʻātoma kalapona, 22 mau ʻātoma hydrogen a me 11 mau ʻātoma oxygen i loko o ka mole mole kino i kapa ʻia ʻo ke kō. Loaʻa i ke kō ke ʻano kemika: C12H22O11. Kapa ʻia ʻo ia he sucrose.
ʻO ka paʻakikī sucrose, lactose a me ka maltose he ʻano kemika maʻamau - C12H22O11
ʻO kekahi kemika i kapa ʻia ʻo ke kō ʻo ka sucrose. ʻO ke kō ke kumu maʻamau o ka sucrose.
ʻAno paʻa - covalent
Hoʻopili nā mea hoʻopaʻa covalent i nā ʻātoma kalapona (C), hydrogen (H), a me ka oxygen (O).
ʻO ke kō wai - aia nā iona manuahi?
Loaʻa ka hoʻonā kō ma ka hoʻokomo ʻana i ke kō i loko o (H2O) wai a hui pono. Loaʻa i nā molekala wai ka hydroxyl (-OH). No laila, hoʻopaʻa nā paʻa hydrogen i nā molekole kō.
ʻAʻole hoʻokaʻawale nā molekala kō, no laila ʻaʻole i haki ka paʻa covalent i loko o nā molekele kō. A ua hoʻokumu ʻia nā paʻa hydrogen hou ma waena o nā molekala a me ka wai.
No laila, ʻaʻohe hoʻololi ʻana o nā electrons ma waena o nā molekala kō. Hoʻopili ʻia kēlā me kēia electron i kona ʻano molekala. ʻO ka hopena, ʻaʻohe iona manuahi e hiki ke hoʻokele i ka uila.
Hiki ke kō i ka uila i ka wai?
ʻO ka electrolyte i loko o kahi hopena electrolytic, e like me NaCl a me KCl, loaʻa kahi paʻa ionic. Hoʻoheheʻe koke lākou i nā ion mobile manuahi ke hoʻohui ʻia iā (H2ʻO) wai, e ʻae iā lākou e neʻe i loko o ka hopena a alakaʻi i ka uila.
I ka lōʻihi o ke kūʻokoʻa ʻana o nā molekala kō, hoʻopiʻi ʻia nā electrolytes.
ʻO ke kō paʻa paʻa - hoʻokele uila?
ʻO ke kalapona, ka hydrogen a me ka oxygen i loko o ke kō i loaʻa ke ʻano kemika C12H22O11, ua hoʻopili ʻia e nā paʻa covalent e like me luna.
- No ka mea, ʻaʻole kūʻokoʻa nā molekala kō, inā mākou e kau i ka uila uila ma luna o kahi aniani kō (paʻa), ʻaʻole e neʻe nā electrons ma ia. Ua like pū ka puʻunaue like ʻana o nā mea paʻa Covalent ma waena o ʻelua mau ʻātoma.
- Noho mau ka electron a ʻo ka mole kōpaʻa e hana ma ke ʻano he insulator no ka mea ʻaʻole polar ka hui.
- ʻO nā ion manuahi, e lawelawe ana ma ke ʻano he mea lawe uila, pono ia no ka hele ʻana o ke au uila. ʻAʻole hiki ke alakaʻi i ka ʻāwī uila ma o kahi paʻakikī kemika me ka ʻole o nā ion mobile.
ʻO kēlā me kēia kemika hiki ke hoʻoheheʻe a hoʻokaʻawale paha i ka wai me ka ʻole o ka hoʻokuʻu ʻana i nā ion i ʻike ʻia he non-electrolyte. ʻAʻole hiki ke alakaʻi ʻia ka uila e kahi mea non-electrolyte i loko o kahi hoʻonā wai.
E nānā i kekahi o kā mākou ʻatikala ma lalo nei.
- Lawe ʻo Sucrose i ka uila
- Na Nitrogen ke alakai i ka uila
- Hiki i ka WD40 ke hana i ka uila?
