Koj puas xa tau raws sijhawm?

Tau kawg! peb tshwj xeeb hauv kab no tau ntau xyoo, ntau tus neeg siv khoom ua ib daim ntawv cog lus nrog kuv vim peb tuaj yeem xa cov khoom raws sijhawm thiab khaws cov khoom zoo tshaj plaws!

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. Cov Txheej Txheem Tseem Ceeb ntawm Sodium dithionite, Sodium hypodisulfite Rongalite
(1) Cov Qauv: Rongalite yog cov ntsev sodium ntawm hydrosulfurous acid thiab feem ntau muaj ob hom: daim ntawv hydrated (Na₂S₂O₄·2H₂O) thiab daim ntawv anhydrous (Na₂S₂O₄). Daim ntawv hydrated tuaj yeem hloov mus rau daim ntawv anhydrous los ntawm kev cua sov kom tshem tawm dej.
(2) Cov Yam Ntxwv ntawm Lub Cev:
a. Sodium dithionite, Sodium hypodisulfiteZoo li: Ib qho hmoov dawb crystalline nrog kev ntws zoo.
b. Qhov Ceev: Qhov ceev tiag tiag yog 2.3–2.4 g/cm³. Qhov ceev ntawm cov khoom sib txawv nyob ntawm txoj kev tsim khoom thiab qhov loj ntawm cov khoom me me: feem ntau yog 1.1–1.25 g/cm³ (Txoj kev siv hmoov Zinc, qhov loj ntawm cov khoom me me 150–200μ); feem ntau yog 0.85–1.1 g/cm³ (Txoj kev siv Sodium formate, qhov loj ntawm cov khoom me me 85–115μ).
c. Sodium dithionite, Sodium hypodisulfite Solubility: Rongalite yaj tau hauv dej tab sis tsis yaj hauv methanol. Nws ib feem decomposes thaum yaj hauv dej. Nws solubility hauv dej nce nrog qhov kub, tab sis txo qis ntau thaum muaj cov tshuaj xws li sodium chloride, sodium hydroxide, lossis cawv.
