Potassium Dichromate CAS 7778-50-9 AR, Assay 99.8%

Potassium Dichromate (CAS: 7778-50-9) muaj zog oxidation thiab corrosion, thiab yuav tov nrog txo tus neeg sawv cev, organic teeb meem, combustible khoom los yog hlau hmoov los ua explosive sib tov, uas yuav ua rau combustion los yog tawg los ntawm kev sib txhuam, kev co los yog cuam tshuam. .
Potassium Dichromate, decomposes tso pa tawm ntawm qhov kub thiab txias, muaj zog oxidation, nws yog ib qho tshuaj lom thiab carcinogenic muaj zog oxidizing tus neeg sawv cev.Nws raug cais raws li pawg I carcinogen los ntawm International Agency for Research on Cancer (IARC) thiab tuaj yeem ntes hluav taws thaum raug hluav taws kub.Vim tias Potassium Dichromate muaj zog oxidizing zog nyob rau hauv acidic tej yam kev mob, nws yog feem ntau siv nyob rau hauv lub chaw soj nstuam los npaj chromic acid ntxuav kua (ib tug sib tov ntawm saturated potassium dichromate tov thiab concentrated sulfuric acid) ntxuav cov tshuaj iav iav kom tshem tawm txo cov av ntawm phab ntsa. nkoj.Tom qab siv, cov tshuaj pleev ib ce hloov los ntawm tsaus liab mus rau ntsuab, thiab cov tshuaj pleev yuav siv tsis tau.Potassium dichromate kuj yog siv rau hauv analytical chemistry, feem ntau yog siv rau kev txiav txim siab ntawm reductive hydrogen sulfuric acid, sulfurous acid, ferrous ion thiab lwm yam.Hauv cua sov, poov tshuaj dichromate tuaj yeem oxidize concentrated hydrochloric acid, tso cov tshuaj chlorine.
Siv nyob rau hauv zus tau tej cov chrome alum, Chromium Oxide Green, chrome daj xim, electrode, luam ntawv number case, kuj siv los ua tanning tus neeg saib xyuas, enamel colorant, luam ntawv thiab Dyeing mordant siv nyob rau hauv zus tau tej cov chrome alum, chrome oxide ntsuab, chrome daj xim.Kev lag luam enamel nrog nws cov hmoov ntev, quartz xuab zeb thiab lwm yam sib xyaw calcined enamel hmoov, raws li cov xim ntsuab.Rau kev npaj cov ntais tshuaj Lub taub hau, los ntawm lub luag hauj lwm ntawm oxidation thiab ya raws.Siv los ua tus neeg sawv cev tanning rau lub teeb tawv.Mordant dyeing thiab luam ntawv yog siv los ua mordant.Cov tshuaj tsw qab hluavtaws tau npaj siv los ua oxidants.Siv rau vuam electrode, luam ntawv number case, hlau passivation.Siv los ua oxidants thiab catalysts hauv organic synthesis thiab raw khoom rau kws tshuaj.
Siv rau hauv kev tsim cov tshuaj chromium, mordant, number case, iav, naj hoom, pigment, ceramics, varnish, explosives, pharmaceuticals, thiab lwm yam.
Siv los ua oxidant, potassium chrome alum thiab siv rau kev npaj cov tshuaj reagents
calibration ntawm sodium thiosulfate txheem daws.Tso cov tshuaj chlorine, oxidants, Chromatography Reagents, organic synthesis.Lub siab ua haujlwm thiab lub gallbladder Performance index tau ntsuas.quav, thiab lwm yam.
Siv raws li siv reagent, redox titrant, chromatography reagent thiab oxidant, kuj siv nyob rau hauv organic synthesis.
