Waikura Basic me ratou āhuatanga

Waikura - he taonga ngā o te ngota hāora i roto i te piti hāora nei ngā rāpoi ngota - 2 me te ngota o te pūmotu tuarua.

Ko te waikura e hanga e e te tauhohenga tika i waenga i te hāora me tetahi atu taonga ranei autaki - i te whāwehe o turanga, tai, waikawa. He tino whānui i roto i te āhua pūhui momo taua, a ka taea e te tīariari i roto i te puka o te hau, wai ranei mārō. kirinuku o te whenua e waikura hoki. Hei tauira, onepu, te waikura, te hauhā , a tae noa te wai mua - he tauira katoa o waikura.

He rite te tote-hanga, me te nesoleobrazuyuschie waikura e. Tote-hanga rite ki te hua o te tauhohenga matū tukua Mariao. Ēnei ngā nga waikura o te konganuku me nonmetals, i roto i te tauhohenga ki te wai ki te hanga i te waikawa, me te tauhohe ki te turanga - te tote, noa, me te waikawa. Ki te tote-hanga ngā, hei tauira, parahi waikura.

Fakatatau ki ai, i te tote nesoleobrazuyuschih taea. Ka rite ki te tauira, te hauhā, dinitrogen waikura, me te hauota ōkai.

E wehea Tote-hanga waikura, i roto i te tahuri, i runga i te taketake, waikawa me te amphoteric. Ka kōrero tatou atu i roto i ngā kōrero e pā ana ki te matua.

Ko te kupu, te waikura taketake - he waikura o etahi konganuku, te waihā e ōrite ana e no ki te piha o turanga. Ko, i te tauhohe i ki te waikawa taua matū hanga te wai, me te tote. Hei tauira, i te reira K2O, cao, MgO, a na i runga i. I roto i te tikanga noa, te waikura taketake e totoka ngā tioata. Tohu whakarewa oksileniya i roto i taua pūhui ko te tikanga e kore atu atu i te rua, e toru onge ranei.

āhuatanga matū o te waikura taketake

1. Reaction ki te waikawa

Ko te reira i roto i te tauhohenga ki te waikura waikawa whakaatu ona āhuatanga taketake, Heoi e taea enei ngā whakamatau te momo waikura ngā. Ki te te tote me te wai i hanga - i konei, he waikura taketake. waikura waikawa i roto i te taua ngā waikawa puka. He taea whakaatu āhuatanga amphoteric ranei waikawa, taketake ranei - tei reira ki runga ki tikanga. Ko nga rerekētanga matua i waenganui i te waikura nesoleobrazuyuschih enei.

2. Reaction ki te wai

I roto i te taunekeneke ki te wai tomo aua waikura o konganuku e kua hanga e he maha o te ngaohiko hiko, anga konupora. Ki runga ki te tauhohenga ki te wai, i whai ahua ai ratou turanga wairewa. Tenei rōpū o waikura whenua kawakore me konganuku alkali (konu waikura, lithium waikura, me ētahi atu). waikura waikawa i roto i te wai ki te hanga i te waikawa, a kahore amphoteric tauhohe ki te wai.

3. Reaction ki waikura waikawa me te amphoteric

Ritenga huru ona waikura āhua matū ki ia atu, ai hanga he tote. Hei tauira, ka taea e waikura taketake ariu ki te waikawa, engari e kore e whakautu ki ētahi atu i te mau melo o to ratou rōpū. Ko te hunga tino kaha he waikura o konganuku alkali, kawakore-whenua me te konupora. Ahakoa i roto i ngā āhuatanga noa, kua tauta ratou ki waikura amphoteric totoka, waikawa mārō, me te haurehu waihā. Ki runga ki te tauhohenga ki waikura waikawa, i whai ahua ai ratou i te tai hāngai.

Ko te waikura taketake o te tahi atu konganuku paruparu, me te whakaritea e kore e tauhohe ki te waikura haurehu waihā (waikawa). Ka taea e ratou anake te tīmata i te tauhohenga hononga mā te alloying ki waikura waikawa mārō.

4. Āhuatanga, pitihāoratanga

e kore e Active waikura konganuku alkali whakaatu āhuatanga whakaiti oxidizing ranei korerotia. I roto i te rerekē, i te waikura e kore e rite e taea konganuku mātātoa ora waro, hauwai, haukini te waro haukura ranei.

Te faaineineraa o waikura taketake

1. waihā whāwehe: turanga rewakore ka ki te hanehane wera whakainu me waikura taketake.

2. hāpiri o konganuku: alkali puka whakarewa waikuratei i roto i parariraa i roto i te hāora, e ka hanga he matua i roto i te whakaiti o te waikura.
