Yog vim li cas vim li cas thiaj muaj qhov sib txawv loj ntawm pH meter thiab pH daim ntawv xeem!
PH daim ntawv xeem: lub hauv paus ntsiab lus yog ua raws li cov tshuaj tiv thaiv xim ntawm qhov taw qhia, uas yog, daim ntawv xeem muaj qee qhov ntsuas qhov ntsuas, thiab thaum nws hloov ntawm ib xim mus rau lwm qhov, nws yuav haus ib qho nyiaj ntawm H ntxiv lossis OH- . Thaum H plus lossis OH hauv cov tshuaj tsis txaus los hloov qhov ntsuas los ntawm ib qho xim mus rau lwm qhov, qhov no yuav ua rau daim ntawv kuaj pH tsis tuaj yeem pom tseeb pH ntawm cov tshuaj.
Tsis daws
Buffering txoj kev xav tau taw qhia tias nyob rau hauv qhov tsis sib xws ntawm cov tshuaj tsis haum, pH ntawm cov tshuaj yog qhov ruaj khov thaum me me ntawm H ntxiv lossis OH- nce lossis txo, uas yog hais, txaus H ntxiv lossis OH- tuaj yeem muab tau. kom tshem tawm pH daim ntawv xeem, tab sis pH ntawm cov tshuaj yog qhov pib tsis hloov pauv, thiab daim ntawv kuaj pH tsis tsim qhov yuam kev.
Thaum qhov pH tiag tiag ntawm cov tshuaj yog dhau qhov tsis muaj qhov sib txawv, me ntsis H ntxiv lossis OH- yuav ua rau muaj kev hloov pauv loj hauv pH ntawm cov tshuaj. Thaum kuaj nrog pH daim ntawv xeem, me ntsis H ntxiv lossis OH- uas ua rau cov pH tiag tiag ntawm cov tshuaj ntau tshaj qhov tsis txaus tsis txaus los hloov cov xim ntawm daim ntawv xeem mus rau qhov pH tiag tiag, thaum lub pH tiag tiag ntawm cov tshuaj. (soaked nrog daim ntawv xeem) tau hloov pauv (rov qab mus rau qhov tsis muaj ntau), thiab daim ntawv xeem pH feem ntau tseem qhia tau tias tus nqi nyob ze ntawm qhov tsis sib xws, ua rau muaj qhov yuam kev.
Cov ntsiab lus
PH daim ntawv xeem siv qee qhov H ntxiv lossis OH-, yog li pH daim ntawv xeem yog qhov ua yuam kev!
Rau cov kev daws teeb meem muaj zog acidic thiab muaj zog alkaline daws, pH daim ntawv xeem feem ntau yuav ua yuam kev.
Daim ntawv xeem pH qhia txog cov khoom ntawm cov tshuaj tsis muaj ntau dua: nyob rau hauv qhov tsis sib xws ntawm qhov tsis muaj qhov system, cov ntawv ntsuas pH qhia qhov tseeb pH ntawm cov tshuaj zoo; Sab nraum qhov tsis sib xws, tus nqi ntawm daim ntawv xeem pH yuav sib txawv ntawm pH ntawm cov tshuaj, uas tuaj yeem ncav cuag ntau qhov pH tiag tiag.
