Cov xim txawv ntawm qhov ntsuas ob xim tsis cuam tshuam los ntawm nws qhov ntau npaum li cas, tab sis vim tias qhov ntsuas nws tus kheej yog kua qaub lossis alkali, qhov hloov pauv ntawm qhov ntsuas tau siv qee yam ntawm titrant, yog li ua rau qhov kev ntsuas yuam kev. Rau ib leeg-xim ntsuas, yog tias tus nqi ntau dhau lawm, cov xim hloov pauv yuav hloov mus rau hauv cov kev taw qhia ntawm pH tus nqi qis, uas yuav ua rau muaj qhov yuam kev titration.
Kev siv ntau npaum li cas ntawm qhov ntsuas yuav cuam tshuam rau qhov rhiab heev ntawm kev hloov xim. Piv txwv li: siv methyl txiv kab ntxwv raws li qhov taw qhia thiab titrating NaOH tov nrog HCl, qhov kawg taw tes yuav yog txiv kab ntxwv. Yog tias siv ntau methyl txiv kab ntxwv, qhov rhiab heev ntawm qhov kawg taw tes yuav tsis zoo.
Dab tsi yog qhov ntau npaum ntawm cov ntsuas tshuaj?
