Qab zib thiab ntsev yog cov piv txwv ntawm soluble tshuaj. Cov tshuaj ntawd tsis yaj hauv dej hu ua insoluble . Xuab zeb thiab hmoov nplej yog cov piv txwv ntawm insoluble tshuaj.
Kuj paub, dab tsi tsis yaj hauv dej?
Ntau yam tshuaj tsis yaj hauv dej thiab qhov ntawd yog vim lawv tsis yog-polar thiab tsis txhob kev sib raug zoo nrog dej molecules. Ib qho piv txwv yog roj thiab dej . Roj muaj cov molecules uas tsis yog-polar, yog li lawv tsis yaj hauv dej . Yog li ntawd ntshiab dej yuav tsis yog ua hluav taws xob.
Ib yam li ntawd, cov khoom dab tsi tsis yaj hauv dej? Ntau yam khoom yuav tsis yaj hauv dej , suav nrog roj, paraffin wax thiab xuab zeb. Cov khoom uas ua yaj hauv dej yuav tsis yaj ib qho ntxiv thaum lawv ncav cuag qhov saturation.
Ua li no, yuav ua li cas yog tias dej tsis yaj cov khoom?
Yog chemical yog soluble hauv dej , ces thaum koj ntxiv rau dej nws yuav yaj , los yog ploj. Yog nws yog tsis yog soluble, ces cov tshuaj yuav tsis yaj thiab koj tuaj yeem pom nws, txawm tias raug tshem tawm hauv dej los yog hauv qab ntawm lub thawv. Thaum twg chemical yog yaj hauv cov kua, xws li dej , nws tsim kev daws teeb meem.
Dab tsi ua rau ib yam dab tsi insoluble hauv dej?
Thaum cov polar compounds los yog ions ntxiv rau dej , lawv tawg mus rau hauv cov khoom me me, lossis yaj, los ua ib feem ntawm cov tshuaj. Cov cov dej ib nrab nqi nyiam qhov sib txawv ntawm cov compound, ua rau lawv soluble nyob rau hauv dej.

Yuav ua li cas yog tag nrho yaj yaj nyob rau hauv lub pas dej ua ke?
Koj cov khoom tawg tag nrho, lossis TDS, tus nqi yog qhov ntsuas ntawm tag nrho cov khoom uas yaj hauv koj lub pas dej. Cov pas dej da dej yuav tsum muaj qhov siab tshaj TDS tus nqi ntawm ib ncig ntawm 1,500 txog 2,000 ppm. Piv txwv li, cov dej haus tuaj yeem muaj qhov siab tshaj TDS tus nqi ntawm 500 ppm raws li EPA
Dab tsi yog ib yam khoom uas yaj los ua ions?
Electrolytes
Yam dab tsi ntawm cov dej zoo tshaj plaws piav qhia nws lub peev xwm los yaj ntau yam khoom siv?
Vim tias nws cov polarity thiab muaj peev xwm tsim cov ntawv cog lus hydrogen, dej ua rau cov kuab tshuaj zoo heev, txhais tau tias nws tuaj yeem yaj ntau hom molecules
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
Dab tsi yog lub npe rau cov khoom uas yaj hauv dej tab sis tsis tsim ions lossis ua hluav taws xob tam sim no?
Ib qho electrolyte yog ib yam khoom uas tsim cov kua hluav taws xob thaum yaj hauv cov kuab tshuaj polar, xws li dej. Cov yaj electrolyte cais mus rau hauv cations thiab anions, uas disperse uniformly los ntawm cov kuab tshuaj. Hluav taws xob, xws li kev daws teeb meem yog nruab nrab
