Cov Khoom Siv Raw rau Copper (II) oxide synthesis

Cov Seights

Thawj cov kev sib tsoo koom nrog synthesis ntawm synthesis ntawm tooj liab (II) yog tooj liab thiab cov pa taws lossis cov duab puab zoo li tooj liab (Cuso4) thiab sodium hydroxide (Naoh). Lub purity ntawm cov reactants cuam tshuam qhov zoo ntawm lub txiaj ntsig tooj liab oxide. Cov chaw tsim khoom thiab cov chaw muag khoom nyiam cov ntaub ntawv nrog cov qib purity tshaj 99% kom ntseeg tau tau zoo hauv cov ntawv thov cov khoom lag luam.

Tshuaj Ntsuam Xyuas Kev Siv Tshuaj

Cov tshuaj tiv thaiv me ntsis

Cov synthesis ntawm tooj liab (II) oxide feem ntau koom nrog thermal decomposition lossis nag lossis daus. Hauv thermal decomposition, tooj hlau yog rhuab nyob rau hauv lub xub ntiag ntawm cov pa, ua rau kev tsim cov huab:

• 2cu + o2 → 2Cuo

Hloov chaw, thaum tooj liab (II) sulfate yog reardfate yog reardfate yog reodium hydroxide, uas ces decomposes los ua tooj liab (II) oxide:

• Cuso4 + 2Nwm → Cu (Oh) 2 + na2SO4
• CU (OH) 2 → Cuo + H2O

Kev Ntsuas Kev Nyab Xeeb Hauv Copper (II) Oxide Kev Tsim Khoom

Ua kom ntseeg txoj kev nyab xeeb

Kev tsim cov tooj liab (II) oxide yuav tsum tau ua kom nruj rau cov kev nyab xeeb rau kev nyab xeeb. Kev tiv thaiv cov hnab looj tes xws li hnab looj tes zoo li hnab looj tes, khawm ci ntsa iab, thiab cov tsho tiv no (lab) yuav tsum siv los tiv thaiv kev sib cuag nrog cov tshuaj corrosive. Qhov chaw dim pa thiab fume hoods yog qhov tseem ceeb kom txo qis kev nqus tau cov pa, tshwj xeeb tshaj yog thaum ua rau cov roj ntsha uas tso tawm roj.

Purification ntawm Reactants thiab cov khoom lag luam

Qhov tseem ceeb ntawm kev coj dawb huv

Rau cov tuam tsev tsim khoom thiab cov chaw muag khoom, kev ua kom huv ntawm tooj liab (II) oxide thiab nws reactants yog qhov tseem ceeb. Impurities tuaj yeem cuam tshuam txog kev siv tshuaj thiab cov xim zoo hauv cov ntawv thov xws li iav kos duab. Cov hau kev xws li recrystallization thiab pom kev ua haujlwm tau ua haujlwm ib txwm ua rau nce qib siab, kom ntseeg tau tias cov khoom kawg tau raws li cov qauv siab.

Muaj tswv yim thiab kev lag luam siv

Tooj liab (II) oxide yog cov kev xaiv nrov rau cov kws ua yeeb yam thiab kev lag luam lag luam zoo ib yam. Nyob rau hauv iav kos duab, ntshaw ua rau kev tsim cov kev hues zoo nkauj ntsuab. Hauv cov lauj kaub, nws ua cov xim rau glazes, muab cov cim tshwj xeeb. Nws lub luag haujlwm hauv kev muab xim zoo sib xws nws qhov tseem ceeb rau kev ua yeeb yam thiab kev lag luam kev lag luam.

Kev Tshaj Tawm Kev Ntsuam Xyuas Cov Tsheb Tooj Liab Oxides

Tooj liab (II) oxide vs. tooj liab (i) oxide

Nkag siab txog qhov sib txawv ntawm tooj liab (II) oxide thiab tooj (i) oxide (cu2o) yog qhov tseem ceeb.
