Hydrogen Peroxide Hydrogen

 

Ntuj hydrogen peroxide:

 

Cov Khoom Siv Lub Cev
1. Tsos thiab Lub Xeev: Hydrogen peroxide yog cov kua tsis muaj kob uas muaj dej ntws, zoo sib xws nrog dej siab dua.
2. Lub ntsiab lus melting yog -0.43 Qib C, ze rau dej.
3. Kev ua txujci hydrogen peroxide tuaj yeem ua kom tsis meej nrog dej, ethanol, thiab ethanol, thiab ua kom yooj yim los npaj cov kev daws teeb meem sib txawv thiab yooj yim rau kev thauj mus los thiab siv.
4. Kev siv hydrogen peroxide feem ntau ntawm kev ua lag luam feem ntau yog cov tshuaj aqueous, thiab cov kev xav tau yog qhia raws li qhov feem pua ​​uas loj. Piv txwv li, lub concortration ntawm hydrogen peroxide feem ntau yog siv rau kev tua kab mob hauv cov khw muag tshuaj yog 3%, uas txhais tau tias txhua 100 lab ntawm h ₂ o ₂. Hauv kev lag luam, muaj cov kev daws teeb meem nrog ntau dua, xws li 30%, 50%, lossis txawm 70%.

 

Tshuaj lom neeg cov khoom (tseem ceeb ntu):
Cov tshuaj lom neeg ntawm hydrogen peroxide yog qhov tsis tshua muaj txiaj ntsig thiab cov yam ntxwv tseem ceeb tuaj yeem yog qhov tseeb uas yog "qhov tsis ruaj khov" thiab "Redox amphoteric".

Cov ntshiab hydrogen peroxide yuav tshwm sim decompose hauv qab lub teeb thiab cua sov tej yam, thiab cov tshuaj tiv thaiv kev tawm tsam yog:
2h ₂ ₂ ₂ (l) → 2h ₂ O (L) + O ₂ (G) + Tshav kub
Qhov kev tawm tsam no yog ib qho kev coj ua ntawm tus kheej -}} kev tawm tsam txo qis thiab muaj extothermic cov tshuaj tiv thaiv.

Oxidation thiab txo (cov yam ntxwv sib deev)
Lub xeev oxidation ntawm cov pa atoms hauv hydrogen peroxules molecules yog -1, uas yog nruab nrab ntawm -2 hauv dej thiab 0 hauv oxygen. Lub Xeev Ib nrab hauv lub xeev feem ntau txiav txim siab tias nws tuaj yeem yog oxidized (rau xoom valence) thiab ua kom muaj kev txo qis; Nws kuj tseem tuaj yeem raug txo (rau -2 qhov tseem ceeb) thiab nthuav tawm oxidizing tej yam. Txawm li cas los xij, feem ntau, tshwj xeeb tshaj yog nyob rau hauv acidic lossis nruab nrab media, nws oxidizing cov khoom muaj txiaj ntsig zoo dua.

Ua tsaug rau koj cov kev mus ntsib thiab tos txais koj cov lus nug zoo!
