Qhov txawv ntawm aqua regia thiab aqua fortis yog aqua regia muaj nitric acid thiab hydrochloric acid, hos aqua fortis yog lwm lub npe rau nitric acid.
Aqua regia yog cov kua qaub thiab corrosive sib xyaw ntawm peb feem ntawm cov concentrated HCl thiab ib feem ntawm cov concentrated HNO 3 Aqua fortis, ntawm qhov tod tes, yog lo lus qub rau nitric. kua qaub. Nws muaj cov tshuaj formula HNO3,thiab nws yog ib qho corrosive thiab txaus ntshai acid.
Aqua Regia yog dab tsi?
Aqua regia yog cov kua qaub thiab corrosive sib xyaw ntawm peb feem ntawm cov concentrated HCl thiab ib feem ntawm cov concentrated HNO3. Yog li ntawd, molar ratio ntawm hydrochloric acid thiab nitric acid yog 1: 3. Qhov sib tov no yog oxidative heev. Cov kua qaub no yog cov kua fuming, thiab thaum npaj tshiab, nws zoo li tsis muaj xim. Tab sis nws hloov daj, txiv kab ntxwv, lossis liab hauv vib nas this. Nws tuaj yeem yaj cov hlau noble kub thiab platinum. Txawm li cas los xij, nws tsis tuaj yeem yaj tag nrho cov hlau.
Daim duab 01: Freshly Npaj Aqua Regia
Aqua regia yog miscible nrog dej. Qhov ceev yog nyob ib ncig ntawm 1.10 g / cm3. Nws cov ntsiab lus melting yog tsawg heev, uas yog nyob ib ncig ntawm -42 degrees Celsius, thiab lub boiling point yog me ntsis siab thiab nyob ib ncig ntawm 108 degrees Celsius.
Thaum xav txog kev npaj cov kua qaub no, qhov sib xyaw ntawm HCl thiab HNO 3 ua rau muaj tshuaj lom neeg tshwm sim thiab tsim nitrosyl chloride thiab chlorine gas. Qhov no yog qhov ua rau cov xim daj thiab fuming xwm ntawm qhov sib tov. Cov khoom volatile no khiav tawm ntawm cov kua qaub, yog li nws poob nws lub peev xwm nrog lub sijhawm. Ntxiv mus, nitrosyl chloride ntxiv decomposes rau hauv nitric oxide thiab elemental chlorine.
Aqua Fortis yog dab tsi?
Aqua fortis yog lub npe archaic rau nitric acid. Nws muaj cov tshuaj formula HNO3,thiab nws yog ib qho corrosive thiab txaus ntshai acid. Aqua fortis tuaj yeem muaj cov tshuaj dilute los yog cov tshuaj muaj zog. Txawm li cas los xij, nws muaj nitric acid molecules yaj hauv dej. Cov tshuaj tiv thaiv ntawm nitrogen dioxide thiab dej tsim nitric acid. Muaj ob hom nitric acid: fuming nitric acid thiab concentrated nitric acid.
Daim duab 02: Fuming Nitric Acid
Fuming nitric acid yog qib kev lag luam ntawm nitric acid uas muaj cov ntsiab lus siab heev thiab ceev ceev. Nws muaj 90-99% HNO3. Peb tuaj yeem npaj cov kua no los ntawm kev ntxiv nitrogen dioxide ntau dhau rau nitric acid. Nws tsim cov xim tsis muaj xim, daj, lossis xim av fuming kua uas yog corrosive heev. Yog li ntawd, cov kua qaub no muaj cov roj molecules ua ke nrog dej; tsis muaj dej hauv nws. Cov pa taws ntawm cov kua qaub no tawm ntawm cov kua qaub; qhov no ua rau nws lub npe, "fuming." Cov tshuaj formula ntawm no compound yog HNO3-xNO2.
Qhov txawv ntawm Aqua Regia thiab Aqua Fortis yog dab tsi?
Aqua regia tuaj yeem piav qhia tias yog acidic thiab corrosive sib xyaw ntawm peb feem ntawm cov concentrated HCl thiab ib feem ntawm cov concentrated HNO3. Aqua fortis yog ib lo lus archaic rau nitric acid thiab yog ib qho corrosive thiab txaus ntshai acid. Yog li ntawd, qhov sib txawv tseem ceeb ntawm aqua regia thiab aqua fortis yog aqua regia muaj nitric acid thiab hydrochloric acid, hos aqua fortis yog nitric acid.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm aqua regia thiab aqua fortis hauv daim ntawv tabular rau kev sib piv ntawm ib sab.
Summary – Aqua Regia vs Aqua Fortis
Cov ntsiab lus aqua regia thiab aqua fortis yog cov ntsiab lus tshwj xeeb rau cov kua qaub. Qhov sib txawv tseem ceeb ntawm aqua regia thiab aqua fortis yog aqua regia muaj nitric acid thiab hydrochloric acid, hos aqua fortis yog nitric acid.
