Xabagta Calcium. guryaha Physical, kulka iyo kiimikada. Codsiga.

Calcium xabagta - xarunta a crystalline cad. Magacyada kale ee walax this - quicklime, xabagta calcium, "Killer Bee", "quicklime". xabagta Calcium kuwaas oo formula Cao, iyo wax soo saarka ay falcelin biyo (H2O) - Ca (OH) 2 ( "pushonka" ama lime cabbid) ayaa helay codsi ballaaran ee ganacsiga dhismaha.

Sida loo helo xabagta calcium?

1. habka Industrial diyaarinta walaxda waa in kaamerada (under kulaylka) ballaarinta nuuradda ah (calcium carbonate) :

CaCO3 (nuuradda) = Cao (calcium xabagta) + CO2 (carbon dioxide)

2. xabagta Calcium sidoo kale waxaa la diyaarin karaa iyada oo ficil walxaha fudud:

2Ca (calcium) + O2 (oxygen) = 2CaO (calcium xabagta)

3. Habka saddexaad ee soo saara xabagta calcium waa kala daatay kaamerada of hydroxide calcium (Ca (OH) 2) iyo calcium cusbada dhowr acids oxygen-ka kooban:

2Ca (NO3) 2 (amooniyam calcium) = 2CaO (walax dheefay) + 4NO2 (xabagta nitrogen) + O2 (oxygen)

guryaha jirka ah ee xabagta calcium

1. Imaansho: Xarunta crystalline midabka cad. Nooca ugu cad chloride sodium (NaCl) in wejiga xuddun daaqaddii crystal cubic.

2. mass gaws of 55,07 grams / jirjirroolaha.

3. cufnaanta waa 3.3 g / santimetr³.

guryaha kaamerada of xabagta calcium

1. heerkulka barafku waa 2570 degrees

2. dhibic The karaya ee 2850 degrees

3. awoodda kulaylka gaws (at xaaladaha caadiga ah) waa 42,06 J / (mol · K)

4. enthalpy ee formation (xaaladaha caadiga ah) ah -635 KJ / mol

The guryaha kiimikada ee xabagta calcium

xabagta Calcium (formula Cao) - waa xabagta a aasaasiga ah. Sidaa darteed, waxay karaan in ay:

- L. biyo (H2O) la sii daayo ee tamarta. Tani foomamka hydroxide calcium. reaction Tani waa sida soo socota:

Cao (calcium xabagta) + H2O (oo biyo ah) = Ca (OH) 2 (calcium hydroxide) + 63.7 KJ / mol;

- fal la acids iyo oxides acid. In this sameeyaan Cusbada leh. Halkan waxaa ku qoran tusaale oo qaar ka mid ah falcelin:

Cao (calcium xabagta) + SO2 (baaruud dioxide) = CaSO3 (calcium sulfite)

Cao (calcium xabagta) + 2HCl (Aashito) = CaCl2 (calcium chloride) + H2O (oo biyo ah).

Isticmaalka xabagta calcium:

1. Muga weyn ee ka hor noo walxaha loo isticmaalo wax soo saarka ee leben silica ee dhismaha. Markii hore, nuurad la gubo loo adeegsaday sida cement lime. Isaga oo loo diyaariyey by it is dhexgalka biyaha (H2O). The xabagta calcium keentay waxaa dhex maray hydroxide taasoo ka dibna, by dhuuqin Hawada dioxide kaarboon (CO2), heer sare ka sii qallafsanaaday, jeestay galay carbonate calcium (CaCO3). Inkastoo qiimaha hooseeyo ee habkan, hadda lime cement waxaa ku dhowaad marnaba loo adeegsado dhismaha, sida uu leeyahay awood u si uu u nuugo oo ku ururto si fiican u dareere ah.

2. wax madax adkaadeen Sida calcia ku haboon sida wax jaban oo si sahlan loo heli karo. Dhisnayd xabagta calcium ayaa iska caabin ah si ay biyaha (H2O), jidaynayey isticmaalkeeda sida madax adkaadeen a, halkaas oo isticmaalka qalabka qaali shaqayn karto.

3. In ay laboratories isticmaalka Maamulaha xabagta calcium for qalajiyo walxaha aan fal la.

4. In warshadaha cuntada maalkii waxa ay u diiwan daro cuntada ka yar E 529. naqshada waxaa loo isticmaalaa sida emulsifier ah abuurka ah ee isku dar ah oo dhqaalaha of non-miscible kasta oo waxyaabaha kale - biyo, saliid iyo dufan.

5. In warshadaha calcium xabagta waxaa loo isticmaalaa in meesha laga saaro dioxide baaruud (SO2) ka gaasas qiiqa. Isticmaalay sida caadiga ah waa 15% xal biyaha. Sidaas darteed of falcelinta taas oo la macaamilaan lime aan biyuhu iyo baaruud dioxide, gypsum helay CaCO4 iyo CaCO3. In tijaabo ah, cilmi doondoonay tilmaame in 98% qiiqa otchistki baaruud dioxide.

6. Waxaa loo adeegsaday in "samogreyuscheysya" gaar ah suxuunta. Markabka la qadar yar oo ah xabagta calcium waxaa u amro labada derbi markabka u dhexeeya. Marka dusaya kaabsal ee reaction biyaha bilaabmaa sii daayo kulaylka qaar ka mid ah.
