Nyob ze li ntawm 110 xyoo dhau los, thaum ua kev sim nrog npias ntawm lub ntiaj teb nto moo Carlsberg tshawb fawb lab hauv Copenhagen, Danish chemist Søren Peter Lauritz Sørensentau tsim qhov yooj yim tab sis tsis ntev pH nplai, uas ntsuas seb cov khoom puas yog acidic lossis yooj yim.
Leej twg tsim pH nplai?
Søren Sørensen. Xyoo 1909 Sørensen, tus kws tshuaj Danish, tau qhia txog lub tswv yim ntawm pH raws li txoj hauv kev yooj yim ntawm kev qhia txog acidity.
PH ntsuas tau li cas?
pH yog lub cav tsis zoo ntawm hydrogen ion concentration hauv cov kua dej. Lo lus "pH" yog thawj zaug piav qhia los ntawm Danish biochemist Søren Peter Lauritz Sørensen hauv xyoo 1909pH yog cov ntawv luv rau "lub zog ntawm hydrogen" qhov "p" luv luv rau lo lus German rau lub zog, potenz thiab H yog lub cim cim rau hydrogen.
Leej twg tsim pH Chav Kawm 10?
Lub tswv yim ntawm pH yog thawj zaug los ntawm tus kws tshuaj Danish Søren Peder Lauritz Sørensen ntawm Carlsberg Laboratory hauv xyoo 1909 thiab hloov kho rau pH niaj hnub hauv xyoo 1924 kom haum rau cov ntsiab lus thiab kev ntsuas hauv Cov ntsiab lus ntawm electrochemical cells.
Yuav ua li cas ob txoj kev ntsuas acidity Soren Sorensen tau npaj?
thawj daim ntawv uas nws siv pH ntsuas tau piav qhia ob txoj hauv kev ntsuas alkalinity, thawj zaug raws li electrodes, thiab qhov thib ob kawm preselected indicators, thiab piv cov qauv xim.
