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

ʻO ka Potassium Dichromate (CAS: 7778-50-9) ikaika ka oxidation a me ka corrosion, a hiki ke hoʻohui ʻia me ka mea hoʻohaʻahaʻa, nā mea kūlohelohe, nā mea puhi a i ʻole ka pauka metala e hana i ka hui pahū, hiki ke hoʻoulu a pahū paha ma ka friction, vibration a i ʻole ka hopena. .
ʻO ka Potassium Dichromate, decomposes e hoʻokuʻu i ka oxygen ma ke keʻokeʻo wela wela, he ikaika ka oxidation, he mea make a me ka carcinogenic ikaika oxidizing agent.Hoʻokaʻawale ʻia ʻo ia ma ke ʻano he carcinogen pūʻulu e ka International Agency for Research on Cancer (IARC) a hiki ke puhi i ke ahi ke ʻike ʻia i nā mea puhi.No ka mea, he mau waiwai oxidizing ikaika ka Potassium Dichromate ma lalo o nā kūlana acidic, hoʻohana mau ʻia ia i loko o ke keʻena hana e hoʻomākaukau ai i ka wai holoi wai chromic (kahi hui ʻana o ka solution potassium dichromate saturated a me ka waikawa sulfuric concentrated) e holoi i nā mea aniani kemika e wehe i ka lepo mai nā paia o ka. moku.Ma hope o ka hoʻohana ʻana, hoʻololi ka lotion mai ka ʻulaʻula ʻeleʻele a hiki i ka ʻōmaʻomaʻo, a ʻaʻole pono ka lotion.Hoʻohana ʻia ka potassium dichromate i ka kemika analytical, i hoʻohana maʻamau ʻia no ka hoʻoholo ʻana i ka waika hydrogen sulfuric reductive, sulfurous acid, ferrous ion a pēlā aku.I ka hoʻomehana ʻana, hiki i ka potassium dichromate ke hoʻohemo i ka waika hydrochloric concentrated, ka hoʻokuʻu ʻana o ka chlorine.
Hoʻohana ʻia i ka hana ʻana o ka chrome alum, Chromium Oxide Green, chrome yellow pigment, electrode, paʻi ʻīnika, hoʻohana pū ʻia e like me ka tanning agent, enamel colorant, paʻi a me ka Dyeing mordant i hoʻohana ʻia i ka hana ʻana i ka chrome alum, chrome oxide green, chrome yellow pigment.ʻO ka ʻoihana enamel me kona pauda lōʻihi, ke one quartz a me nā pauka enamel calcined hui ʻia, ma ke ʻano he kala ʻōmaʻomaʻo.No ka hoʻomākaukau ʻana i nā pāʻani Medicine Head, mai ka hana o ka oxidation a me ka makū.Hoʻohana ʻia ma ke ʻano he tanning agent no ka ʻili māmā.Hoʻohana ʻia ke kala a me ka paʻi ʻana ma ke ʻano he mordant.Ua hoʻomākaukau ʻia nā mea ʻala synthetic no ka hoʻohana ʻana ma ke ʻano he oxidants.Hoʻohana ʻia no ka welding electrode, paʻi ʻīnika, metala passivation.Hoʻohana ʻia e like me nā oxidants a me nā catalysts i ka synthesis organik a me nā mea maka no nā lāʻau lapaʻau.
Hoʻohana ʻia i ka hana ʻana i nā kemika chromium, mordant, inika, aniani, ʻala, puaʻa, keramika, varnish, explosives, pharmaceuticals, etc.
Hoʻohana ʻia ma ke ʻano he oxidant, potassium chrome alum a me ka kuhikuhi no ka hoʻomākaukau ʻana i nā reagents kemika
calibration o ka sodium thiosulfate solutions maʻamau.Hoʻokuʻu i ka nānā ʻana o ka chlorine, oxidants, Chromatography Reagents, organic synthesis.Ua ana ʻia ka hana o ka ate a me ka helu o ka gallbladder.Stool, etc.
Hoʻohana ʻia e like me ka reagent reference, redox titrant, chromatography reagent a me ka oxidant, hoʻohana pū ʻia i ka synthesis organik.
