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

Potaziyamu Dichromate (CAS: 7778-50-9) imakhala ndi okosijeni wamphamvu komanso dzimbiri, ndipo imatha kusakanizidwa ndi zinthu zochepetsera, organic, zinthu zoyaka kapena chitsulo chachitsulo kuti mupange kusakanikirana kophulika, komwe kungayambitse kuyaka kapena kuphulika ndi kugunda, kugwedezeka kapena kukhudzidwa. .
Potaziyamu Dichromate, amawola kutulutsa mpweya pa kutentha koyera, ali ndi okosijeni wamphamvu, ndi poizoni ndi carcinogenic wamphamvu oxidizing wothandizira.Imasankhidwa kukhala gulu loyamba la carcinogen ndi International Agency for Research on Cancer (IARC) ndipo imatha kupsa ndi moto ikakumana ndi zoyaka.Chifukwa Potaziyamu Dichromate ili ndi oxidizing amphamvu pansi pa mikhalidwe ya acidic, imagwiritsidwa ntchito mu labotale pokonzekera chromic acid wash solution (osakaniza a saturated potaziyamu dichromate solution ndi concentrated sulfuric acid) kutsuka magalasi a mankhwala kuti achotse zinyalala pamakoma a chombo.Mukagwiritsidwa ntchito, mafuta odzola amasintha kuchokera ku mdima wofiira kupita ku wobiriwira, ndipo mafuta odzola adzakhala osagwira ntchito.Potaziyamu dichromate imagwiritsidwanso ntchito mu chemistry yowunikira, yomwe imagwiritsidwa ntchito pozindikira kuchuluka kwa reductive hydrogen sulfuric acid, sulfurous acid, ferrous ion ndi zina zotero.Potentha, potaziyamu dichromate imathanso oxidize hydrochloric acid, kutulutsidwa kwa chlorine.
Amagwiritsidwa ntchito popanga chrome alum, Chromium Oxide Green, chrome yellow pigment, elekitirodi, inki yosindikizira, imagwiritsidwanso ntchito ngati pofufuta, utoto wa enamel, kusindikiza ndi Dyeing mordant omwe amagwiritsidwa ntchito popanga chrome alum, chrome oxide wobiriwira, chrome yellow pigment.Makampani a enamel ndi ufa wake wautali, mchenga wa quartz ndi ufa wina wosakanikirana wa enamel, monga mtundu wobiriwira.Pokonzekera machesi Medicine Head, kuchokera udindo wa okosijeni ndi chinyezi.Amagwiritsidwa ntchito ngati chowotchera chikopa chopepuka.Kupaka utoto wa Mordant ndi kusindikiza kumagwiritsidwa ntchito ngati mordant.Mafuta onunkhira amapangidwa kuti azigwiritsidwa ntchito ngati okosijeni.Amagwiritsidwa ntchito powotcherera ma elekitirodi, inki yosindikiza, passivation yachitsulo.Amagwiritsidwa ntchito ngati ma oxidants ndi othandizira mu organic synthesis ndi zida zopangira mankhwala.
Amagwiritsidwa ntchito popanga mankhwala a chromium, mordant, inki, galasi, mafuta onunkhira, pigment, zoumba, varnish, zophulika, mankhwala, etc.
Amagwiritsidwa ntchito ngati okosijeni, potaziyamu chrome alum ndikufotokozera pokonzekera ma reagents amankhwala
ma calibration a sodium thiosulfate standard solutions.Kutsitsa kusanthula kwa chlorine, okosijeni, Chromatography Reagents, organic synthesis.Kugwira ntchito kwa chiwindi ndi index ya ndulu zinayesedwa.Chotupa, etc.
Amagwiritsidwa ntchito ngati reagent redox, redox titrant, chromatography reagent ndi oxidant, amagwiritsidwanso ntchito popanga organic synthesis.
