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 ntawm peb cov neeg muag khoom kom tau txais cov ntaub ntawv qhia txog kev txiav txim, thiab peb yuav piav qhia txog cov txheej txheem kom ntxaws. Kev txhais thiab cov khoom siv tshuaj lom neeg
Cov khoom siv tshuaj lom neeg ntawm cov kua qaub oxalic feem ntau yog pom tseeb hauv nws cov acidity thiab reducibility. Raws li dibasic acid, oxalic acid dhau los ua ob kauj ruam dissociation, nrog rau thawj qhov dissociation tas mus li ntawm kwv yees li
5.9 × 10−2
thiab qhov thib ob dissociation tsis hloov pauv ntawm txog
6.4 × 10−5
(raws li Phau Ntawv Qhia Txog Organic Chemistry). Nws cov kua qaub muaj zog ua rau nws yaj tau cov hlau oxides zoo. Hauv cov tshuaj redox, oxalic acid yooj yim oxidized los ntawm cov neeg sawv cev oxidizing muaj zog xws li potassium permanganate los tsim cov pa roj carbon dioxide thiab dej, ua rau nws feem ntau siv ua tus neeg sawv cev txo qis hauv kev tshuaj xyuas tshuaj.
Ob pawg carboxyl hauv cov molecule oxalic acid nyob rau ntawm cov pa roj carbon uas nyob ib sab, thiab cov qauv tshwj xeeb no muab nws lub peev xwm sib koom tes zoo heev, ua rau nws tsim cov khoom sib xyaw ruaj khov nrog cov hlau ions xws li hlau thiab txhuas. Qhov tseem ceeb, calcium oxalate tsis yaj hauv dej - ib yam khoom uas muaj qhov tseem ceeb hauv kev kho mob hauv cov txheej txheem ntawm kev tsim pob zeb hauv lub raum. Thaum cua sov tshaj 150 ° C, cov kua qaub oxalic acid yuav lwj los tsim cov kua qaub formic, carbon monoxide, thiab lwm yam khoom, yog li yuav tsum zam cov chaw kub siab thaum khaws cia.
