Basabela kanjani CaCl2, H2SO4

Omunye izikhubekiso ngezinyathelo lokuqala ukutadisha imithetho zamakhemikhali izisekelo ukubhala zamakhemikhali. Ngakho-ke, imibuzo mayelana nokuxhumana CaCl2, H2SO4 awukho njalo futhi ngendlela ehlelekile. Ake sihlole main "inkinga" zikhathi.

Record kwesibalo yamangqamuzana

Ukuxhumana phakathi calcium chloride (usawoti) kanye sulfuric acid odabula indlela exchange.

Kuyizimpawu okunjena yilezi:

• uxhumano amabili ngesikhathi itheku (impahla eluhlaza);
• uxhumano ezimbili ngesikhathi okukhipha (umkhiqizo);
• ukungabakhathaleli nhlobo izinto ezilula.

Kushintshaniswa nomunye amaqembu esisheshayo, le reactants kuthiwa kushintshwe okuthile kulo bese ezothando kuthatha ifomu:

CaCl2 + H2SO4 = CaSO4 + 2HCl.

Njengoba singabona, izidakamizwa ezimbili eziyinkimbinkimbi, ukushintsha ion akha compounds ezahlukene kakhulu: usawoti entsha (CaSO4) futhi hydrochloric acid (HCl).

Ukuze ageleze kuze kube sekupheleni

Phendula lo mbuzo kungaba nje ngokubhalela CaCl2, H2SO4 yokusabela ezothando ngefomu yamangqamuzana ezinto eziphilayo. Uhlobo imikhiqizo ngeke sithembele. Kuze kube sekupheleni nqubo esimweni imfundo:

• ndaba encibilikayo (kodaka);
• kwakwakhe oluyingozi (igesi);
• reagent malodissotsiiruschego (amanzi, electrolyte ababuthakathaka).

Ngo ukucabangela CaCl2, H2SO4 Uma kwenzeka kuba khona phakathi calcium sulfate imikhiqizo ukuphendula - kwakwakhe kabi encibilikayo kusheshisa ngokuvumelana etafuleni.

Ngenxa yalokho, inqubo exchange izobanjelwa kuze kube sekupheleni.

Lichazwa ifomu ionic phakathi ukuqoshwa CaCl2, H2SO4

Ukubhala izinto zonke compounds encibilikayo ku ion kanye nokunciphisa okuvela amaqembu esisheshayo, sithola zibalo ezimbili engaziwa:

• gcwalisa ifomu ionic ukuqopha phakathi CaCl2, H2SO4

^{ca 2+ + 2cl - + 2 amahora +} + ngakho ₄ ^2- = caso ₄ ⁺ 2 amahora + 2cl ^-

• isifushaniso ezothando

ca ²⁺ + ngakho ₄ ^2- = caso _4.

Kufanele kukhunjulwe ukuthi ion kuphela zaveza nosawoti encibilikayo, acid, lezisekelo (lokhu kunqunywa kalula lolutfolakala kumathebula ekhethekile). Engaqinile electrolyte uhlobo carbonic noma acetic acid njalo yalotshwa njengezingoma zohlobo oluthile yamangqamuzana ezinto eziphilayo.

Manje uyazi ukuthi kube khona ukusebenzisana phakathi calcium chloride (usawoti), futhi i-sulfuric acid.
