Haukinia tote - tikanga o te faaineineraa, te whakamahi i roto i te ōhanga motu

Ko te pūhui matū o NH4 + faaite ake rite te māraa ļa whakarewa alkali pai putawa i ako. A, no te pāhekoheko ki ng ngota o matū waikawa e hanga e te hanganga tioata c - Salt Haukini pākawa NH4N03, NH4C1 pūhaumāota, pūkawa ngāwha (NH4) 2S04, e ngā o te anion waikawa me te rōpū te haukinia.

tai haukinia whiwhi i roto i te tauhohe neutralization, e puta i roto i te tauhohe o te haukini me te waikawa.

haukinia tai, pērā i, i roto i te parau tumu, te nuinga o te whakarewa alkali dissociate kia (wahia ki tīhiko me ng ngota) i roto i te wairewa i runga i te katote: tai haukinia, tai whakarewa rite alkali dissociate ki katote:

NH4N03 ↔ NH4 ++ NO3-

I roto i te whakawera, kua decomposed tai haukinia maroke ki haukini me te waikawa; huaina ana tēnei tukanga ko waiariki dissociation.

Ko te waikawa i hanga (hei tauira, te waikawa pūhaumāota) tahi ki evaporates NH3 me ki runga ki tautauā herea ki haukini me te whiwhi he tote te. Me mea te reira e ko te reira taea, me te tukanga he whāwehe reversible:

NH3 + HCl ↔ NH4Cl

Ko te kupu, sublimes haukinia pūhaumāota ka hana, engari etahi wa i runga i te tihi o te ngongo i muri i puta ano paninga ma o te haukini pūhaumāota. Ka rite ki te hua, te hanganga o tai waikawa kore-ahua, hei tauira, (NH4) 2S04, volatilizes i roto i te para anake NH3, a ka noho tonu te waikawa. huaina ana tēnei tukanga ko te whāwehe tina heke.

E ngā decomposed tai haukinia katoa e kawakore (ki whakawera) ki te tuku haukini:

NH4 + + OH -↔NH3 ↑ + H20

Kei te whakamahia i tēnei tauhohenga mō te rapunga o maniua ki te puka haukinia o hauota.

I roto i te tauhohenga o te haukini pākawa ki kohuke me waikawa organic tukua te hauhā. I roto i te tauhohenga o te haukini pākawa ngāwhā pūhaumāota ranei ki AgNO3 BaCl ranei i hanga tīwharawhara tae ma āhuatanga.

tai haukinia: Tauira

tai haukinia whānui e whakamahia ana i roto i te ahuwhenua. Ko te rauemi pai mō te tipu kai kohuke tenei (hei tauira, te haukini pākawa ngāwhā - (NH4) 2S04). Ka rite ki te mea i mohiotia he taea tipu Nitrogen mimiti anake i roto i te puka here (NO3, NH4). Na reira, he tino whai hua nga pūhui hauota. O te faufaa nui ko te pākawa te haukinia e Kei roto haukini pākawa NH4 NO3- hauota.

Na haukinia dihydrogen Phosphate, mohiotia i raro i nga ingoa o MAP NH4H2P04 me diammonium Phosphate (NH4) 2NR04 roto i ngā āhuatanga e rua matū o te tipu kai tōtika - Nitrogen me ūkuikui. ngā tai haukini i roto i te maniua whakauru.

A, no te tauhohe haukini ki te waro waikura (IV) i synthesized Urea Urea NH2-CO-NH2 ranei.

Haukinia pūhaumāota (NH4C1) haukini pūhaumāota ranei e whakamahia i roto i ngā pūtau iahiko, i roto i te tae me te sittsepechatanii, tinning me te whakapiringa. Whakapā i te whakarewa wera, kua decomposed haukini ki hauwai pūhaumāota me te haukini. waikawa pūhaumāota tauhohe ki te waikura, poke te mata whakarewa, i hanga ai te te tote ahua.

Me kï reira e ki te mata horoia pai piri tūhoto. NH4NO3 (haukini pākawa) tahi ki te waro me te konumohe tai he wahi o te taikaha - ammonal. E whakamahia ana ēnei pūhui i te whanaketanga o kamaka. Haukinia hydrogencarbonate Kei te maha (NH4NSO3) whakamahia i roto i te ahumahi kai, me te rare. Kei te whakamahia hoki tenei pūhui rite te rokiroki mō ngā momo rerekē o te kai. He āhuatanga e āwhina whakatere maoa NH4HCO3 denitrofitsiruyuschimi.

tauhohenga kounga ki haukinia tote. A, no te tahu, i hanga te tai haukini ki otinga alkali o haukinia waihā, piri nei ki te tuku o te haukini.

taea ana te ruri te aroaro o te haukini i te kakara motuhake, me te ki tohu pepa tae. Hoki e mau ana i roto i tēnei tauhohenga ko reira e tika ana ki te tango i 1.0 cm3 haukinia otinga tote tāpiri 0.5 cm3 otinga o te konutai waihā me te wera. I roto i te tukanga whakawera, kua tukua haukini, i hanga kakara āhuatanga te, whero he waikawa puru.
