Kev ntsuas pH yog kev ntsuas txheeb ze. Nws tsuas yog qhia qhov sib txawv ntawm pH ntawm cov qauv kev daws teeb meem thiab tsis paub daws teeb meem. Hauv kev ntsuas qhov tseeb, ib qho kev daws teeb meem tsis zoo yuav tsum tau ntsuas tsis tu ncua. Yog li ntawd, txhawm rau kom ua tiav tus nqi tib yam, yuav tsum tau tsim pH nplai. Lub pH nplai ntau yog teem rau ntawm 0-14pH, thiab tus nqi ntawm pH nplai yog txiav txim los ntawm pHs tus nqi ntawm cov ntaub ntawv tsis siv tshuaj.
Yog li ntawd, lub ntsiab lus ntawm pH nplai tuaj yeem qhia tau tias: Raws li lub ntsiab lus ntawm pH, xaiv ntau lub pH tsis haum rau hauv thaj tsam ntawm 0 mus rau 14 pH raws li cov ntsiab lus ruaj khov ntawm pH nplai, thiab siv ntau tshaj. txoj kev raug uas tuaj yeem ua tiav los ntawm cov cuab yeej siv niaj hnub los txiav txim siab lawv cov pHs. tus nqi. Muaj ob hom pH nplai hauv ntiaj teb, uas yog ntau yam siv pH nplai thiab ib qho kev siv pH nplai. Tuam Tshoj siv ntau qhov ntsuas pHs.
pH tsis haum tshuaj
Cov tshuaj pH tsis yog cov tshuaj uas tuaj yeem ua kom tus nqi pH ruaj khov. Yog hais tias ib qho me me ntawm cov kua qaub los yog alkali ntxiv rau cov tshuaj no, los yog ib qho me me ntawm cov kua qaub los yog alkali yog tsim los ntawm cov tshuaj tiv thaiv hauv cov tshuaj, thiab cov tshuaj yog diluted tsim nyog, pH tus nqi ntawm cov tshuaj yog qhov ruaj khov, uas. tuaj yeem tiv taus cov kua qaub me me Los yog alkali lossis dilution, thiab ua rau pH tus nqi nyuaj los hloov cov tshuaj hu ua pH tsis yog tshuaj.
Cov tshuaj pH txheem tsis muaj cov yam ntxwv hauv qab no:
⑴ The pH value of the standard solution is known and reaches the specified accuracy.
⑵The pH value of the standard solution has good reproducibility and stability, with a larger buffer capacity, a smaller dilution value and a smaller temperature coefficient.
⑶ The preparation method of the solution is simple.
