Txoj Kev Titration Propionic Acid
Npaj cov khoom siv iav xws li lub burette thiab lub raj mis conical. Piv txwv li, yog tias koj txiav txim siab txog cov ntsiab lus ntawm propionic acid hauv cov khoom lag luam propionic acid, koj yuav tsum ntsuas qhov hnyav ntawm cov qauv propionic acid thiab muab tso rau hauv lub raj mis conical. Ntxiv cov dej distilled kom raug kom yaj cov qauv tag nrho. Tom qab ntawd xaiv cov cim qhia uas haum, xws li phenolphthalein. Titrate nrog cov tshuaj sodium hydroxide uas paub tias muaj concentration. Thaum lub sijhawm titration, qhov kev tsis sib haum xeeb tshwm sim ntawm sodium hydroxide thiab propionic acid. Thaum ntxiv sodium hydroxide, pH ntawm cov tshuaj maj mam nce. Qhov kawg ntawm titration yog thaum cov xim ntawm cov tshuaj hloov ntawm tsis muaj xim mus rau liab dawb thiab tseem tsis hloov pauv rau ib nrab feeb. Raws li qhov ntim ntawm cov tshuaj sodium hydroxide uas koj noj, cov ntsiab lus ntawm propionic acid hauv cov qauv tuaj yeem suav tau los ntawm kev sib raug zoo stoichiometric. Cov mis tshwj xeeb yog los ntawm cov tshuaj sib npaug rau cov tshuaj tiv thaiv ntawm propionic acid thiab sodium hydroxide, uas muaj qhov sib piv stoichiometric ntawm 1: 1, hloov pauv siv cov mis molar concentration thiab pawg.info@pulisichem.cn
