Ntawm dilution lub tus naj npawb ntawm ions ib chav tsev ntim txo. Li no, cov conductivity txo.
Yuav ua li cas rau diluting cov tshuaj electrolyte?
Ntawm diluting cov tshuaj ntawm ib qho electrolyte ∧ nce thiab k txo.
Thaum ib qho electrolyte yog diluted?
Kev coj ua hloov pauv nrog qhov concentration ntawm electrolyte. Ntawm dilution li ntim ntawm cov tshuaj nce. Yog li, tus naj npawb ntawm ions ib ml txo qis thiab yog li conductivity txo. Molar conductivity yog txhais rau 1 mole ntawm ions.
Yuav ua li cas hauv qab no txo qis dilution ntawm cov tshuaj electrolyte?
Tus naj npawb ntawm ions ib cc txo nrog dilution thiab yog li ntawd, tshwj xeeb conductancetxo qis nrog dilution.
Qhov twg ntawm cov khoom nram qab no ntawm cov tshuaj electrolyte nce rau ntawm dilution?
Cov conductivity nce ntxiv raws li kev dilution.

Ib qho ntawm cov hauv qab no yog cov piv txwv ntawm cov lus pom zoo rau huab cua?
Cov kws tshawb fawb tau paub txog ntau qhov kev tawm tswv yim zoo hauv kev nyab xeeb. Ib qho piv txwv yog melting ice. Vim tias cov dej khov muaj lub teeb-xim thiab muaj kev cuam tshuam, feem ntau ntawm cov hnub ci uas tsoo nws tau rov qab mus rau qhov chaw, uas txwv qhov kub ntawm qhov nws ua rau.
Cov piv txwv ntawm cov kuab tshuaj thiab cov kuab tshuaj yog dab tsi?
Solutes yog cov khoom uas yaj rau hauv cov kuab tshuaj thiab peb xaus nrog kev daws. Qee qhov piv txwv ntawm cov kuab tshuaj yog dej, ethanol, toluene, chloroform, acetone, mis nyuj, thiab lwm yam. Piv txwv ntawm cov kuab tshuaj muaj xws li, qab zib, ntsev, oxygen, thiab lwm yam … Cov dej dej muaj dej (kua kua) thiab yaj oxygen (solute).
Hauv kev tshuaj ntsuam organoleptic cov tshuaj raug tshuaj xyuas los ntawm?
Kev ntsuas tshuaj muaj ntau txoj hauv kev uas yuav raug cais raws li hauv qab no: Organoleptic thiab morphological kev ntsuam xyuas: Kev ntsuam xyuas los ntawm txhais tau tias ntawm lub cev ntawm kev nkag siab paubxim, tsw, saj, qhov loj me, cov duab thiab cov yam ntxwv tshwj xeeb xws li kev ntxhib los mos.
Thaum tus txheej txheem ntawm diluting ib qho kev daws rau qhov qis dua?
Thaum tus txheej txheem ntawm diluting ib qho kev daws kom qis dua, tus nqi ntawm cov kuab tshuaj tsis hloov. Cov tshuaj uas muaj qhov concentration ntawm 2 M yog diluted kom nws cov ntim tshiab yog plaub npaug ntawm cov ntim qub. Yuav ua li cas thaum lub sijhawm diluting cov tshuaj kom qis dua?
Cov tshuaj twg yog cov tshuaj uas tsis yog tshuaj tiv thaiv inflammatory analgesic?
Txhua yam koj yuav tsum paub txog NSAIDs. Nonsteroidal anti-inflammatory tshuaj (NSAIDs) yog cov tshuaj uas txo qis lossis txo qhov mob. Cov piv txwv nrov tshaj plaws ntawm cov tshuaj hauv pawg no yog aspirin thiab ibuprofen. NSAIDs tuaj nyob rau hauv lub ntsiab lus dav ntawm non-opioid analgesics.
