Thaum cov tshuaj tsis muaj zog electrolyte yog diluted, qhov ntim ntawm cov tshuaj nce, yog li qhov sib npaug conductivity (λc) nce. Txawm li cas los xij, thaum tus txheej txheem no, tus naj npawb ntawm cov khoom nqa tam sim no ib cm3 txo.
Yuav ua li cas thaum tsis muaj zog electrolyte yog diluted?
Rau qhov tsis muaj zog electrolyte molar conductance hauv cov tshuaj dilute nce sharply raws li nws cov concentration hauv cov tshuaj txo.
Yuav ua li cas rau hluav taws xob conductivity ntawm qaug zog electrolyte nrog dilution?
Rau cov electrolytes tsis muaj zog (piv txwv li cov electrolytes tsis tiav), txawm li cas los xij, cov molar conductivity zoo nyob ntawm qhov concentration: Qhov ntau dilute cov tshuaj, qhov ntau dua nws cov molar conductivity, vim nce ionic dissociation.
Ib qho piv txwv ntawm cov electrolyte tsis muaj zog yog dab tsi?
Tsis muaj zog electrolytes ib nrab dissociate rau hauv ions hauv kev daws thiab yog cov hluav taws xob tsis muaj zog. Hom tsis muaj zog electrolytes muaj xws li qaug zog acids thiab bases. Piv txwv ntawm cov electrolytes tsis muaj zog muaj xws li acetic acid thiab mercury(II) chloride.
Vim li cas dissociation ntawm qaug zog electrolyte nce nrog dilution?
Hint: Cov degree ntawm dissociation ntawm ib tug tsis muaj zog electrolyte yog ncaj qha proportional rau lub square cag ntawm dilution vim hais tias ntawm dilution, nws dissociates rau hauv ions vim lub siab dielectric tas li ntawm dej los yog hnyav thiab ionstau nkag tau yooj yim yog li nce qib ntawm kev sib cais.

Vim li cas ib tug noog perched ntawm ib tug high voltage hlau tsis tua los ntawm tam sim no?
Thaum ib tug noog nyob ntawm ib lub xaim, nws ob txhais taw yog tib yam hluav taws xob, yog li cov electrons hauv cov xov hlau tsis muaj kev txhawb nqa mus nciglos ntawm tus noog lub cev. Tsis muaj hluav taws xob txav txhais tau tias tsis muaj hluav taws xob tam sim no .
Puas cov khoom tsis muaj zog puas muaj zog?
Ib pawg tsis muaj zog tuaj yeem muaj zog E thiab lub zog p vim huab hwm coj cuam tshuam nrog cov kab zauv m 2 =E 2 /c 4 - p 2 /c 2 , uas yog xoom rau photon vim E=pc rau huab cua tsis muaj zog. Puas yog cov khoom tsis muaj zog muaj zog?
Ua li cas cov khoom tsis muaj zog muaj lub zog?
Ib pawg tsis muaj zog tuaj yeem muaj lub zog E thiab lub zog p vim tias huab hwm coj cuam tshuam nrog cov no los ntawm kev sib npaug m 2 =E 2 /c 4 - p 2 /c 2, uas yog xoom rau photon vim E=pc rau huab cua tsis muaj zog . Yuav ua li cas cov khoom loj tsis muaj zog?
Puas muaj kev sib cav uas tsis muaj zog thiab tsis muaj kev ntseeg?
Puas muaj kev sib cav uas tsis muaj zog thiab tsis muaj kev ntseeg? piav qhia: Txhua qhov kev sib cav uas tsis muaj zog kuj yuav tsis muaj kev sib cav, vim tias yuav muaj zog yog ib feem ntawm lub ntsiab lus ntawm kev sib cav . Puas muaj kev sib cav uas tsis muaj zog thiab paub?
Puas yuav suav tias yog cov electrolyte tsis muaj zog?
Ib tug tsis muaj zog electrolyte yog ib electrolyte uas tsis tas dissociate nyob rau hauv aqueous tovCov tshuaj yuav muaj ob qho tib si ions thiab molecules ntawm cov electrolyte. Tsis muaj zog electrolytes tsuas yog ib feem ionize hauv dej (feem ntau 1% mus rau 10%), thaum muaj zog electrolytes tag ionize (100%) .
