1. Qhov ntau thiab tsawg

Muaj feem xyuam rau kev txiav txim siab ntawm cov kua qaub formic hauv kev lag luam.

2. Txoj Kev Ntsuas
2.1 Kev Txheeb Xyuas Cov Ntsiab Lus Formic Acid
2.1.1 Lub Ntsiab Cai
Formic acid yog ib qho kua qaub tsis muaj zog thiab tuaj yeem titrated nrog cov kua NaOH txheem siv phenolphthalein ua tus qhia. Cov tshuaj tiv thaiv yog raws li nram no:
HCOOH + NaOH → HCOONa + H₂O

Cov khoom siv zog ntawm cov kua qaub Formic acid, muaj cov ntaub ntawv, nyem qhov no kom tau txais cov nqi luv nqi txij lub Yim Hli mus txog rau lub Kaum Hli.
