Amphoteric ke hooheheeia, a me ko lakou waiwai

Amphoteric ke hooheheeia - i na mea waiwai i loko o nā hale a, Nine Inch a me physical waiwai like ai i ua poe la o ka mea hao hehee ai pae. Ma o lakou iho, i ka mea hiki ke hooheheeia hiki ole e amphoteric waiwai, ma ka Akä naÿe i kā lākou i huiʻia. No ka laʻana, oxides a me hydroxides o kekahi mea hiki ke hooheheeia i pālua Nine Inch ano - i loko o kekahi mau kumu a lakou hoi e like me nāʻakika, a i ka waiwai'ē aʻe alkalis.

XIX. Amphoteric ke hooheheeia - ka Aluminum, kiniki, chromium, a me ka hao. Kēia pūʻulu o ka oihana mua nā beryllium a me ka strontium.

He aha ka amphoteric?

No ka manawa mua, i ike i ka lōʻihi manawa kahiko keia waiwai. A me ka manawa "amphoteric hehee wale" Ua wahahee i ka 1814 ma ka 'epekema ma ka pono ike chemists thenar a me L. J. Māhū-Lussac. I ia mau lā, i ka Nine Inch hui hoʻohana 'ia e mahele ia i loko o nā pūʻulu i halawai lākou walaʻauʻana waiwai i ka naoh.

Aka hoi, i ka pae ana o oxides a me nā kumu waiwai a pālua akamai. Ma lalo o kekahi rula, na waiwai hoi i mekala 'åkilikai' ē aʻe, ma ka mea ku ole, hana like nāʻakika. I ka manawa "amphoteric" a pela i ala hou mai. No kēia mau Nine Inch hana iloko oʻakika-kumu naoh hilinaʻi nui ma luna o na olelo o kona manaʻo, i ke ano o na reactants āpau i komo i like loa me ka waiwai o ka'ūheheʻe.

Interestingly, ma ka vivo amphoteric ke hooheheeia e pāʻani aku me nā ka mekala 'åkilikai a me kaʻakika. No ka laʻana, iloko o ka naoh me ka Aluminum sulufahateʻakika hua Aluminum sulufahate. A i loko o ka naoh o ka ia me ka ikaika mekala 'åkilikai metala luna' paakai ua hana.

Amphoteric kumu, a me kā lākou mau kumu waiwai

Ma lalo o maʻamau rula, i kēia puaʻa hiwa. Ka mea, kokoke mai i hoike mai i ka wai, a ua manaoia, aole i nawaliwali electrolytes.

Ke kumu o hana no ka loaa ana o ia mau kumu, - i ka mea hiki ke hooheheeia paakai ma ka naoh me ka uuku nui o ka mekala 'åkilikai. Kimu naoh E e lawe mai lohi a akahele. No ka laʻana, ma ka makaukau o ke kiniki hydroxide i loko o ka hōʻike şarkı me kiniki koloriside akahele hou dropwise paʻakai hydroxide. Kēlā me kēia manawa e pono e iki e lulu i ka ipu, e ike i ke keʻokeʻo metala sediment ma ka lalo o nā ipu.

Me nāʻakika a me ka ʻakika oxides amphoteric waiwai pane koke me ke kumu. No ka laʻana, ka naoh o kiniki hydroxide me ka hydrochloricʻakika ua i hanaʻia o ka kiniki koloriside.

Akā, ma ka reactions me nā kumu amphoteric kumu hele me nāʻakika.

No hoi, ka wā ikaika paio hahana maoli nō amphoteric hydroxides i decomposed e hana i ka like amphoteric'okesaside a me ka wai.

Ka loa, he pono ole amphoteric ke hooheheeia: he manawa pōkole hōʻikeʻano

Kiniki pili ia i kekahi pūʻulu o amphoteric hehee wale. Oiai oka a pau o keia mea i ua hoʻomano hoʻohana i kahiko maikai ana, i loko o kona maemae ano mea hiki ke hōʻike 'wale i ka 1746.

Ka maemae metala Ua lawa ka brittle mea bluish waihoʻoluʻu. I ka lewa hoʻomaka koke oxidized kiniki - pō mai kona ili, a uhi i ka lahilahi Auana o'okesaside.

Ma ke ano maoli, kiniki i koe puleʻAmelika, i loko o ka palapala o nā minelala hao - zincite, smithsonite, Calamita. Ka maikai-ike mea - keia blende, a he o kiniki sulfide. Ka nui loa hoʻokomo kālā o kēia mea pōhaku i loaʻa i loko o Bolivia a me Australia.

Aluminum mea i keia la noʻonoʻo i ka loa nui metala ma ka Honua. Kona oka a i ua hoʻohana no kenekulia, a ma ka makahiki 1825 i kaʻawale ka waiwai i loko o ke gula palapala.

Pure Aluminum mea he Lightweight metala kālā. He hoopuni mīkini penei: a me ka hoike ana. Kēia hehee ai, ua kiʻekiʻe uila a me ka thermal conductivity. Eia kekahi, ua hiki ke hooheheeia mea hoʻopale ai i ka popopo. Ka mea i ua uhiia kona ili me ka lahilahi akā loa hoʻopale'okesaside ho film.

I ka lā, Aluminum ua hoʻomano hoʻohana 'ia i loko o ka hana.
