Puas yog calcium chloride ua hluav taws xob?

Puas yog calcium chloride ua hluav taws xob? Hauv tsab xov xwm no, kuv yuav pab koj nrhiav cov lus teb.

Peb paub txog sodium chloride lossis cov ntsev ntsev, tab sis tsis yog calcium chloride. Ob qho calcium chloride thiab sodium chloride yog hlau chlorides. Txawm li cas los xij, calcium thiab sodium (los yog lwm yam hlau chloride) muaj cov tshuaj sib txawv, uas tuaj yeem ua rau tsis meej pem. Chemistry ntawm hlau chlorides yog qhov tseem ceeb rau kev nkag siab tias ions ua hluav taws xob li cas.

Feem ntau, thaum cov nplej ntsev yaj, nws cov ions tsis sib xws (cov ntsiab lus uas ua rau cov ntsev-calcium thiab chloride ions, nyob rau hauv peb cov ntaub ntawv) yog dawb txav mus rau hauv kev daws, tso cai rau tus nqi ntws. Txij li thaum nws muaj ions, qhov kev daws teeb meem yuav ua hluav taws xob.

Saib hauv qab no kom paub meej ntxiv.

Puas yog calcium chloride yog cov khoom siv hluav taws xob zoo?

Calcium chloride nyob rau hauv lub xeev molten yog ib tug zoo conductor ntawm hluav taws xob. Calcium chloride yog ib tug tsis zoo conductor ntawm tshav kub. Kub taw tes 1935 ° C. Nws yog hygroscopic thiab absorbs noo noo los ntawm huab cua.

Vim li cas cov tshuaj calcium chloride ua hluav taws xob?

Cov tshuaj calcium chloride muaj cov ions mobile uas hloov cov nqi lossis hluav taws xob.

Thaum cov ntsev yaj, nws cov ions dissociated (cov ntsiab lus uas ua rau cov ntsev-calcium thiab chloride ions, nyob rau hauv peb cov ntaub ntawv) yog dawb mus nyob ib ncig ntawm cov tshuaj, tso cai rau tus nqi ntws. Txij li thaum nws muaj ions, qhov kev daws teeb meem yuav ua hluav taws xob.

Vim li cas sodium chloride (NaCl) thiaj li ua tau zoo?

Dej thiab lwm yam polar compounds dissolve NaCl. Cov dej molecules nyob ib puag ncig txhua cation (tus nqi zoo) thiab anion (tus nqi tsis zoo). Txhua ion yog absorbed los ntawm rau dej molecules.

Ionic tebchaw nyob rau hauv lub xeev cov khoom, xws li NaCl, muaj lawv cov ions nyob rau hauv ib txoj hauj lwm thiab yog li ntawd txav tsis tau. Yog li, cov khoom siv ionic tsis tuaj yeem ua hluav taws xob. Ions nyob rau hauv ionic tebchaw yog mobile los yog dawb ntws thaum molten, yog li molten NaCl tuaj yeem ua hluav taws xob.

Vim li cas calcium chloride (CaCl) ua hluav taws xob ntau dua li sodium chloride (NaCl)?

Calcium chloride muaj ntau ions (3) dua li sodium chloride (2).

Vim NaCl muaj ob ions thiab CaCl2 muaj peb ions. CaCl yog cov concentrated tshaj plaws thiab yog li ntawd muaj qhov ua tau zoo tshaj plaws. NaCl yog qhov tsawg tshaj plaws (piv rau CaCl) thiab muaj qhov hluav taws xob qis tshaj plaws.

Sodium chloride vs calcium chloride

Hauv cov ntsiab lus, alkaline ntsev tebchaw muaj xws li calcium chloride thiab sodium chloride. Ob leeg ntawm cov tebchaw no muaj chloride ions, tab sis nyob rau hauv sib txawv proportions. Qhov sib txawv tseem ceeb ntawm calcium chloride thiab sodium chloride ntsev yog tias txhua lub calcium chloride molecule muaj ob chlorine atoms whereas txhua sodium chloride molecule muaj ib.

Cov lus nug nquag nug

Vim li cas sodium chloride tsuas ua hluav taws xob thaum molten?

Hauv ib qho chaw ionic, xws li NaCl chloride, tsis muaj hluav taws xob dawb. Muaj zog electrostatic zog khi electrons ua ke nyob rau hauv daim ntawv cog lus. Yog li, sodium chloride tsis ua hluav taws xob hauv lub xeev khoom. Yog li, lub xub ntiag ntawm mobile ions txiav txim qhov conductivity ntawm NaCl nyob rau hauv lub molten lub xeev.

Puas yog calcium chloride lossis sodium chloride nyiam rau cov dej khov yaj?

Calcium chloride (CaCl) tuaj yeem yaj cov dej khov ntawm -20 ° F, uas yog qis dua qhov melting point ntawm lwm yam dej khov yaj. NaCl tsuas yog yaj mus txog 20 ° F. Thiab nyob rau lub caij ntuj no, nyob rau hauv feem ntau ntawm sab qaum teb xeev ntawm Tebchaws Meskas, qhov kub thiab txias poob qis dua 20 ° F.

Puas yog calcium chloride lawm hygroscopic?

Anhydrous calcium chloride, los yog calcium dichloride, yog calcium chloride ionic compound. Nws muaj crystalline khoom dawb xim ntawm ambient kub. (298 K). Nws yog hygroscopic vim nws dissolves zoo nyob rau hauv dej.

Yam dab tsi cuam tshuam rau solubility? Xav txog cov lus nug nram qab no: Puas yog calcium chloride soluble ntau dua li barium chloride?

Kev coj tus kheej yog txiav txim siab los ntawm kev txav mus los ntawm cov ions, thiab cov ions me me feem ntau yog mobile.

Thaum hais txog cov dej molecules, lawv feem ntau txhais tau tias cov txheej txheem dej.

Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
