Konganuku Amphoteric me ratou āhuatanga

konganuku Amphoteric - he matū ohie e i roto i te hanganga, matū me ngā āhuatanga ōkiko rite ki te hunga o te rōpū huānga konganuku. E ratou, e kore e taea e te konganuku hei āhuatanga amphoteric, i roto i te rerekē ki ratou pūhui. Hei tauira, waikura, ngā waihā o etahi konganuku i āhua matū rua - i roto i etahi tikanga tikanga ratou rite waikawa me whai āhuatanga ētahi atu kawakore.

Basic konganuku amphoteric - he konumohe, konutea, chromium, me te rino. Tenei rōpū o ngā huānga ngā teriuma me te strontium.

He aha te mea amphoteric?

Hoki te wa tuatahi, i kitea tenei taonga te wa roa i mua. Na te wā "huānga amphoteric" i whakaurua i te tau 1814 i roto i te pūtaiao i thenar Utaina pai mohiotia ko L. J. Gay-Lussac. I aua ra, i te pūhui matū e whakamahia ana ki te kia wehea ki ngā rōpū e tutaki ratou āhuatanga taketake i roto i te tauhohenga.

Otiia, i te rōpū o waikura me turanga riro kaha rua. I raro i te tahi mau tikanga, tikanga rite alkali atu taua matū, i runga i te anga ke, hei waikawa. Ko te wā "amphoteric" me pera whakatika. Hoki enei matū whanonga i roto i te waikawa-turanga tauhohenga tei runga i te tikanga o tona whakatinanatanga, te āhua o te matū hohe whai wāhi rite te pai kia rite ki te āhuatanga o te whakarewa.

Mea faahiahia, i roto i te vivo e taea konganuku amphoteric taunekeneke ki e rua te alkali me te waikawa. Hei tauira, i roto i te tauhohe ki te konumohe waikawa pūkawa hua konumohe pākawa ngāwhā. A i roto i te tauhohe o te taua ki te whakarewa alkali tote kaha matatini i hanga te.

turanga Amphoteric me ratou āhuatanga taketake

I raro i ngā āhuatanga noa, tenei totoka. Ratou e kore i whakaritea e memeha i roto i te wai, me te e whakaaro electrolytes kaua ngoikore.

Ko te tikanga taketake mō te whiwhi taua turanga - he tote whakarewa i te tauhohenga ki te nui iti o alkali. kia kawea whakauruhi tauhohenga i āta, me te āta. Hei tauira, i roto i te faaineineraa o te konutea waihā i roto i te ipuipu ki te konutea pūhaumāota āta tāpiri konutai waihā dropwise. Ia wa e hiahia ana koe ki te paku ruru te ipu ki te kite i te waipara whakarewa ma i te raro o rihi.

Ki te waikawa me waikura waikawa ariu matū amphoteric rite te turanga. Hei tauira, i hanga te tauhohenga o te konutea waihā ki te waikawa pūhaumāota te o konutea pūhaumāota.

Otiia i roto i nga tauhohe ki turanga tikanga turanga amphoteric rite waikawa.

Ano, ka whakawera kaha waihā amphoteric e decomposed ki te hanga i te waikura amphoteric me te wai hāngai.

Ko te konganuku amphoteric tino noa: he whakamārama poto

e pā ana te konutea ki te rōpū o ngā āhuatanga amphoteric. Ahakoa alloys o tenei rauemi kua whakamahia whānuitia i roto i u'i i tahito ra, i roto i tona puka parakore taea te tāutuhia reira anake i roto i te 1746.

Ko makona te whakarewa parakore he pakarukaru rauemi tae kikorangi. I roto i te hau tere oxidized konutea - to kurupae i tona mata, me te hipoki ki te kiriata angiangi o te waikura.

I roto i te natura, te vai te nuinga konutea i te puka o kohuke - zincite, smithsonite, Calamita. Ko te rauemi pai-mohiotia - tenei blende, e ngā o konutea sulfide. E kitea ana te putunga nui o tenei kohuke i roto i Bolivia me Ahitereiria.

whakaaro konumohe Ko tenei ra te whakarewa nui tino i runga i te ao. Kua ona alloys whakamahia mō ngā rau tau, me te i roto i 1825 taratahi te taonga i roto i te puka parakore.

konumohe Pure ko te hiriwa whakarewa Kōmāmā. Ia ngāwari machined me makanga. Tenei huānga he kawe ia hiko, me te ngāwhā tiketike. I tua atu, he ātete ki te waikura tenei whakarewa. Ko te take i hipoki tona mata e ki te kiriata waikura angiangi engari rawa ātete.

Ki te rā, kei te whānui e whakamahia ana konumohe i roto i te ahumahi.
