Carbonate, hydroxide kanye calcium carbonate

Calcium ... Yini oyaziyo ngaye? "Lokhu metal", - nje ukuphendula abaningi. Futhi kuthiwani-calcium compounds khona? Ngalesi wonke umuntu iphuzu uzoqala ukuzinwaya ikhanda lakho. Yebo, singathola ulwazi kwaphela mayelana esidlule, futhi ngaye calcium kakhulu. Kulungile, ake sixoxe kamuva, kodwa okwamanje ake sibheke okungenani ezintathu ezibangela yayo - carbonate, hydroxide kanye calcium carbonate.

1. calcium carbonate

Kuyinto usawoti ezakhiwe calcium carbonic acid ezisalayo okuyinto. Ifomula carbonate - Caco _3.

izakhiwo

It has ngesimo powder emhlophe okuyinto zingaxazululeki ngamanzi ETHYL utshwala.

Ukulungiselela-calcium carbonate

Kumiswa It is ngesikhathi calcination-calcium oxide. Ukuze yokugcina, amanzi ingezwe, bese emva ikhambi okuholela -calcium hydroxide Kwenziwa-carbon dioxide. Imikhiqizo ukuphendula kukhona carbonate oyifunayo namanzi, ahlukaniswa kalula kusuka komunye nomunye. Lapho ukufuthelana, kuyoba cleavage imikhiqizo elaliyoba carbon dioxide futhi quicklime. Lapho kuqedwa carbonate ne-carbon monoxide (II) ingalungiswa emanzini nge-calcium carbonate. Uma sihlanganisa i-carbon futhi nge-calcium carbonate, imikhiqizo ye-yokusabela kukhona calcium Carbide ne-carbon monoxide.

isicelo

Lokhu carbonate - wokulinganisa uwukuba sihlangane njalo uhlangabezana ezikoleni kanye nezinye imfundo yamabanga aphansi naphakathi ephakeme. Futhi, basuke mhlophe ophahleni, zaveza entwasahlobo ka zemithi futhi wenza inhlabathi eziyisisekelo in ukulima umkhakha.

2. calcium Bicarbonate

Kuyinto usawoti carbonic acid. Ingabe ifomula Ca (HCO _{3) 2.}

izakhiwo

amanzi encibilikayo, njengazo zonke hydrocarbon. Nokho, kuyinto isikhathi esithile kwenza kube nzima. Ngo eziphilayo, i-calcium carbonate nezinye nosawoti, abanye kusukela ezizivelelayo esifanayo babe umsebenzi nabalawuli ka njalo igazi ukusabela.

reception

It is etholwe ukusabela carbon dioxide, i-calcium carbonate namanzi.

isicelo

Sitholakala amanzi okuphuza, lapho emakamu zingahluka - kusuka 30 kuya 400 mg / l.

3. Calcium hydroxide

Formula - Ca (OH) _2. Le into is a sizindza lesicinile. Ngo imithombo ehlukahlukene kungaba ukubiza lime slaked noma "fluff".

reception

Kumiswa It is ngesikhathi asabela ngayo calcium oxide namanzi.

izakhiwo

Anakho ngesimo powder emhlophe, kancane oncibilikayo emanzini. Nge lokushisa okwandisa, lokugcina value kwamanani we solubility incipha. Futhi-ke uyakwazi iwukudambisa acid imiswe phakathi neminyaka ukusabela elihambisana calcium usawoti namanzi. Uma wanezela kuso ziyoncibilika emanzini, isikhutha etholakala wonke amanzi efanayo, kodwa futhi nge-calcium carbonate. Nge ukuqhubeka barbotatsii CO ₂ intando calcium carbonate kumiswa.

isicelo

Bona mhlophe ikamelo, ezicijile lokhuni, kanye camera semishayweni. Ngale ekulungiseleleni hydroxide ngodaka lwe-lime, bleach, umquba ekhethekile, lime ukhonkolo, futhi ngisho ukuqeda carbonate nobulukhuni amanzi (sashintsha yokugcina). Ngalesi izidakamizwa eyenziwa causticization potassium ne-sodium carbonates, zokukhipha igciwane impande emiseleni amazinyo, futhi aphilise isikhumba Tan izifo abanye isitshalo. calcium hydroxide, eyaziwa ngokuthi yi- E526 ukudla okufakiwe.

isiphetho

Manje uqonde ukuthi kungani kulesi sihloko nganquma ukuchaza lezi zinto ezintathu? Phela, lezi zakhi "etholakele" nomunye ngesikhathi ukuwathuthukisa kokuthola ngamunye wabo. Kukhona nezinye izinto eziningi engahlobene, kodwa ukukhuluma ngesinye isikhathi.
