Poov tshuaj Dichromate (K₂CRORO₇)
Feem ntau yog paub txog poov tshuaj bhromate lossis liab prussiate ntawm potash. Nws zoo li txiv kab ntxwv-liab triclay lossis rab muaj muaju, nrog lub ntsej muag melting ntawm 398 degree ntawm 500 degree (dur degree (decomposes thaum boiling). Nws yog soluble hauv dej, sib sau ua ib qho kev daws teeb meem kua qaub nrog cov xeb, tshuaj lom, thiab muaj zog oxidizing tej yam.
Sodium dichromate (nau-₂cr₂₂₇₂)
Feem ntau yog hais tias sodium bichromate lossis liab prussiate ntawm dej qab zib. Nws tshwm sim ua cov liab monoclinic prismatic lossis rab muaj muaju, nrog lub ntsej muag melting, nrog lub ntsej muag melting ntawm 300 degree ntawm 600 degree (decostraignes thaum boiling). Ntawm 100 degree, nws poob cov crystal dej los ua cov ntawv anhydrous (na₂crrous₇), uas muaj lub ntsiab lus melting ntawm 357 degree ntawm 400 degree thaum tso oxygen. Sodium Dichromate yog cov hygroscopate muaj txiaj ntsig zoo nkauj, thiab nws cov kua aidic, lom zem, lom neeg ua kom muaj zog oxidizing tej yam.
Cov Lus Tseem Ceeb:
Ob lub tebchaw yog carcinogenic thiab yuav tsum tau tuav txoj kev nyab xeeb nruj vim lawv cov tshuaj lom thiab muaj kev phom sij ib puag ncig.
Lawv cov khoom siv oxidizizy ua rau lawv muaj kev puas tsuaj thaum sib chwv nrog cov khoom sib luag lossis cov khoom siv organic.
Cov khib nyiab pov tseg khib nyiab thiab ib puag ncig ib puag ncig yuav tsum nruj me ntsis ua raws li los tiv thaiv cov hlau muaj kuab paug hnyav.
