Acetoneyog ib tug polar organic hnyav nrog ib tug molecular mis ntawm CH3COCH3.Nws pH tsis yog tus nqi tas li tab sis nws txawv nyob ntawm nws cov concentration thiab lwm yam.Feem ntau, ntshiab acetone muaj pH ze rau 7, uas yog nruab nrab.Txawm li cas los xij, yog tias koj dilute nws nrog dej, tus nqi pH yuav tsawg dua 7 thiab ua acidic vim yog pawg ionizable hauv cov molecule.Nyob rau tib lub sijhawm, yog tias koj sib xyaw acetone nrog lwm cov tshuaj acidic, tus nqi pH kuj yuav hloov raws li.

Txhawm rau txiav txim siab pH tus nqi ntawm acetone, koj tuaj yeem siv pH meter lossis pH ntawv.Ua ntej, koj yuav tsum npaj ib qho kev daws ntawm acetone nrog ib qho concentration.Koj tuaj yeem siv cov ntshiab acetone los yog dilute nrog dej raws li koj xav tau.Tom qab ntawd, koj tuaj yeem siv pH meter lossis pH ntawv los ntsuas nws tus nqi pH.Nco ntsoov tias pH meter yuav tsum tau ntsuas ua ntej siv los xyuas kom meej qhov ntsuas tau.

Ntxiv nrog rau qhov concentration thiab kev sib xyaw ua ke, pH tus nqi ntawm acetone kuj tseem cuam tshuam los ntawm qhov kub thiab txias thiab lwm yam.Acetone nws tus kheej yog volatile heev, thiab cov concentration thiab pH tus nqi yuav txawv nrog cov kev hloov ntawm kub thiab siab.Yog li ntawd, yog tias koj xav tau kom raug tswj hwm tus nqi pH ntawm acetone hauv cov txheej txheem qee yam, koj yuav tsum coj mus rau hauv tus account ntau yam ua tiav los xyuas kom meej qhov tseeb thiab ruaj khov ntawm qhov kev sim.

Hauv cov ntsiab lus, pH tus nqi ntawm acetone cuam tshuam los ntawm ntau yam, suav nrog kev sib xyaw, kev sib xyaw, kub thiab lwm yam.Yog li ntawd, peb yuav tsum tau sim thiab ntsuas pH tus nqi ntawm acetone nyob rau hauv cov xwm txheej sib txawv kom ntseeg tau tias qhov ntsuas tau raug.
