Qhov sib txawv tseem ceeb ntawm hydrogen fluoride thiab hydrofluoric acid yog hydrogen fluoride yog ib qho inorganic compound whereas hydrofluoric acid yog cov tshuaj hydrogen fluoride hauv dej.
Ob leeg hydrogen fluoride thiab hydrofluoric acid muaj tib yam tshuaj formula, HF, uas muaj hydrogen atom thiab fluorine atom. Txawm li cas los xij, cov no yog ob nqe lus sib txawv nyob ntawm cov khoom siv tshuaj thiab lub cev. Yog li, ntawm no, peb yuav tham txog qhov sib txawv ntawm hydrogen fluoride thiab hydrofluoric acid.
Hydrogen Fluoride yog dab tsi?
Hydrogen fluoride yog cov tshuaj chemical uas muaj cov tshuaj formula HF. Nws muaj hydrogen atom thiab fluorine atom sib koom ua ke ntawm covalent daim ntawv cog lus. Nws yog ib tug diatomic molecule, tab sis nyob rau hauv nws cov khoom, muaj zig-zag HF chains. Cov HF chains no yog tsim vim muaj zog hydrogen bonds uas tsim ntawm HF molecules. Daim ntawv ua kua kuj muaj cov qauv no. Qee qhov tseeb ntawm cov tshuaj no muaj raws li hauv qab no:
- Molar mass yog 20 g / mol
- Nws tshwm sim raws li cov roj tsis muaj xim; lub xeev ua kua kuj tsis muaj xim
- Lub ntsiab lus melting yog −83.6 ° C thaum lub boiling point yog 19.5 ° C
- Vim lub peev xwm ntawm HF los tsim cov ntawv cog lus hydrogen, cov khoom sib xyaw no yog miscible tag nrho nrog dej
Peb tuaj yeem tsim cov tshuaj no los ntawm cov tshuaj tiv thaiv ntawm sulfuric acid thiab qib ntshiab ntawm cov ntxhia "fluorite". Txawm li cas los xij, feem ntau HF yog tsim los ntawm cov khoom siv chiv. Muaj ob peb qhov tseem ceeb siv HF; Raws li cov khoom ua ntej rau organofluorine tebchaw, ua cov khoom ua ntej rau hlau fluorides, ua catalyst, ua hnyav, thiab lwm yam.
Hydrofluoric Acid yog dab tsi?
Hydrofluoric acid yog cov tshuaj aqueous ntawm HF. Qhov ntawd txhais tau tias nws yog kev daws teeb meem ntawm hydrogen fluoride hauv dej. Peb tuaj yeem sau cov qauv tshuaj raws li HF(aq) Nws zoo li cov tshuaj tsis muaj xim. Tsis tas li ntawd, qhov kev daws teeb meem no yog miscible nrog dej. Lub npe IUPC rau cov tshuaj no yog Fluorane. Cov tshuaj yog cov kua qaub qaug zog vim lub zog ntawm H-F daim ntawv cog lus thiab tsim cov pawg ntawm HF, H2O thiab F–
Tsis tas li ntawd, peb tuaj yeem tsim cov kua qaub tsis muaj zog no los ntawm kev kho cov ntxhia fluorite nrog sulfuric acid. Muaj ntau hom kev siv rau hydrofluoric acid. Cov ntawv thov suav nrog kev foob cov roj refining, tsim cov organofluorine tebchaw, tsim cov fluorides, ua cov tshuaj ntxuav, thiab lwm yam.
Qhov txawv ntawm Hydrogen Fluoride thiab Hydrofluoric Acid yog dab tsi?
Sib piv cov khoom ntawm hydrogen fluoride thiab hydrofluoric acid, qhov sib txawv tseem ceeb ntawm hydrogen fluoride thiab hydrofluoric acid yog hydrogen fluoride yog ib qho inorganic compound whereas hydrofluoric acid yog ib qho kev daws ntawm hydrogen fluoride hauv dej. Yog li, hydrogen fluoride muaj H thiab F atoms, thaum hydrofluoric acid muaj HF molecules hauv dej.
Cov duab hauv qab no muab cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm hydrogen fluoride thiab hydrofluoric acid.
Summary – Hydrogen Fluoride vs Hydrofluoric Acid
Hauv cov ntsiab lus, hydrogen fluoride thiab hydrofluoric acid yog ob hom sib txawv ntawm tib lub ntsiab lus. Qhov tseem ceeb, qhov sib txawv tseem ceeb ntawm hydrogen fluoride thiab hydrofluoric acid yog hydrogen fluoride yog ib qho inorganic compound whereas hydrofluoric acid yog ib qho kev daws ntawm hydrogen fluoride hauv dej.
