Vim NaCl muaj ob ions, CaCl 2 muaj 3 ions, thiab AlCl3 muaj 4 ions, AlCl3 yuav yog feem ntau concentrated nrog lub siab tshaj plaws conductivity thiab NaCl yuav yog qhov tsawg tshaj plaws concentrated nrog qis tshaj conductivity . Vim nws dissociates tag nrho, nws yuav tsim ntau ions hauv dej.

Ua raws li qhov no, puas yog CaCl2 tus neeg xyuas pib zoo ntawm hluav taws xob?

Qhov ntom ntawm calcium chloride yog 2.15 gm/cm³. Nws yog soluble ob qho tib si hauv cov kuab tshuaj inorganic zoo li dej, nrog rau cov kuab tshuaj organic xws li ethanol. Feem ntau nyob rau hauv lub xeev molten, nws yog a zoo conductor ntawm hluav taws xob . Calcium chloride yog phem tus thawj coj ntawm tshav kub.

Tom qab ntawd, lo lus nug yog, vim li cas NaCl conductive hauv dej? Common rooj ntsev ( NaCl ) yog ib qho electrolyte, thiab thaum qhov no yog yaj hauv dej ua ntsev dej , nws dhau los ua sodium ions (Na⁺) thiab chloride ions (Cl^-), txhua tus uas yog lub cev uas ua hluav taws xob. Hauv dej , nws yog cov ions uas kis hluav taws xob los ntawm ib qho mus rau lwm qhov.

Hais txog qhov no, yog vim li cas KCl yog cov conductive tshaj NaCl?

Nws yuav yog Li>Na>K me me, ntau qhov sib npaug ionic conductance. Qhov ntawd tsuas yog ib qho quab yuam, K + ion loj dua tshaj Na + ion, yog li qhov kev ncua deb ntawm K + thiab Cl-ions yog loj dua nruab nrab ntawm Na + thiab Cl-, txo lub zog ntawm daim ntawv cog lus. Yog lawm, KCl muaj ib tug high bond zog, tab sis tsis siab li NaCl.

Dab tsi yog qhov conductivity ntawm NaCl?

Kev hloov dua siab tshiab ntawm conductivity rau tag nrho cov yaj yaj nyob ntawm cov tshuaj muaj pes tsawg leeg ntawm cov qauv thiab tuaj yeem sib txawv ntawm 0.54 thiab 0.96. Feem ntau, kev hloov dua siab tshiab yog ua tiav piv txwv tias cov khoom yog sodium chloride , i.e., 1 ΜS / cm ces sib npaug li 0.64 mg ntawm NaCl ib kg dej.
