Kuv puas tuaj yeem mus xyuas koj lub tuam txhab thiab lub Hoobkas hauv Suav teb?

Tseeb. Koj zoo siab tos txais koj tuaj xyuas peb lub tuam txhab hauv Zibo, Suav teb. (1.5H tsav tsheb los ntawm Jinan)

Kuv tuaj yeem tso qhov kev txiav txim li cas?

Koj tuaj yeem xa peb cov lus nug rau ib tus neeg sawv cev muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia txog cov txheej txheem kom ntxaws. Lub Npe Tshawb Fawb thiab Cov Qauv Tshuaj Oxalic Acid
Lub Koom Haum Thoob Ntiaj Teb ntawm Kev Tshawb Fawb Txog Tshuaj Pure thiab Siv (IUPAC) hu nws ua ethanedioic acid, uas yog ib qho kev txhais lus ncaj qha uas qhia txog nws cov qauv ntawm ob pawg carboxyl txuas ncaj qha. Cov ntawv qhia txog tshuaj lom neeg Suav thoob ntiaj teb siv cāo suān ua lub npe pom zoo. Nws cov mis molecular yog H₂C₂O₄, nrog rau qhov hnyav molecular ntawm 90.04. Thaum sov chav tsev, nws zoo li cov siv lead ua pob tshab tsis muaj xim, yooj yim yaj hauv dej (kwv yees li 14 g yaj hauv 100 mL dej ntawm 25 ° C). Cov tshuaj no feem ntau muag ua dihydrate (H₂C₂O₄·2H₂O). Thaum cua sov txog li 100 ° C, nws poob nws cov dej ntawm crystallization; cua sov ntxiv ua rau nws lwj mus rau hauv formic acid thiab carbon dioxide. Kev ua tus tswv ntawm qhov kev poob phaus thermal no tso cai rau qhov sib txawv sai ntawm anhydrous oxalic acid thiab oxalic acid dihydrate hauv chav kuaj mob los ntawm kev tshuaj xyuas gravimetric yooj yim, zam kev siv cov khoom siv raw hydrated hauv cov qauv kev lag luam uas xav tau anhydrous crystals, uas yuav ua rau cov tshuaj tiv thaiv txo qis lossis cov khoom lag luam nce ntxiv.
