Igama Lomkhiqizo:I-nitric acid
Ifomethi ye-molecular:HNO3
Inombolo ye-CAS:7697-37-2
Isakhiwo samangqamuzana omkhiqizo:
Izakhiwo Zekhemikhali:
I-nitric acid iwuketshezi olufuthekayo olungenambala ukuya kokunsundu ngokukhanyayo olunephunga elimuncu, eliminyanisayo. I-nitric acid evuthayo iwuketshezi oluvuthayo olubomvu. Intuthu emoyeni onomswakama. Ngokuvamile isetshenziswa isixazululo aqueous. I-nitric acid evuthayo i-nitric acid egxilile equkethe i-nitrogen dioxide encibilikisiwe. I-nitric acid iyisisombululo se-nitrogen dioxide, i-NO2, emanzini futhi okuthiwa i-fuming nitric acid iqukethe okweqile kwe-NO2 futhi inombala ophuzi kuya kobomvu ngokubomvu.
Uketshezi olungenambala; ukugqwala kakhulu; inkomba ye-refractive 1.397 ku-16.5 ° C; ukuminyana 1.503 g/L; iqhwa ku -42°C; amathumba ku-83 ° C; hlanganisa ngokuphelele namanzi; yakha i-azeotrope ebilisa njalo ngamanzi ku-68.8 wt% nitric acid; i-azeotrope inokuminyana okungu-1.41 g/mL futhi ibilisa ku-121°C.
Isicelo:
I-nitric acid iyisici esibalulekile sokuqala ukukhiqizwa kukamanyolo namakhemikhali. I-nitric acid ehlanjululwe isetshenziselwa ukuncibilikisa kanye nokufaka i-metals Product DataSheet
Lolu ketshezi olusindayo, olucacile noma oluphuzi kancane lunoshevu futhi ludala ukusha okukhulu lapho uthinta isikhumba. Yenziwe ngokuchithwa kwe-alkali-metal nitrate ehlanganiswe ne-sulfuric acid. Inhlanganisela ye-nitric ne-sulfuric acid yasetshenziswa ukuguqula ukotini ongenalutho ku-cellulose nitrate. I-nitric acid yasetshenziswa enqubweni yepuleti elimanzi njengesengezo kubathuthukisi be-ferrous sulfate ukukhuthaza umbala omhlophe wesithombe sama-ambrotypes nama-ferrotypes. Iphinde yengezwa ukuze kwehliswe i-pH yokugeza okuyisiliva kumapuleti e-collodion. Ukwengeza i-asidi kubhavu oyisiliva kwenza amapuleti e-collodion angazweli ekukhanyeni, okube nomthelela onenzuzo wokunciphisa ukwenzeka kwenkungu engeyona yesithombe.
