Hydrogen Chloride vs Hydrochloric Acid
Peb ib txwm txheeb xyuas cov kua qaub ua tus pub dawb proton. Acids muaj qaub saj. Txiv qaub kua txiv, vinegar yog ob tug acids peb tuaj nyob rau hauv peb lub tsev. Lawv hnov mob nrog cov hauv paus ua dej, thiab lawv kuj ua rau cov hlau ua H 2, yog li nce hlau corrosion. Cov kua qaub tuaj yeem muab faib ua ob, raws li lawv lub peev xwm los sib cais thiab tsim cov protons. Cov kua qaub muaj zog yog ua tiav ionized hauv cov tshuaj, muab cov protons. Cov acids tsis muaj zog yog ib feem dissociates thiab muab cov protons tsawg dua. Ka yog cov kua qaub dissociation tas li. Nws muab ib qho kev qhia txog lub peev xwm los poob ib tug proton ntawm ib tug qaug zog acid.
txhawm rau xyuas seb cov khoom puas yog cov kua qaub lossis tsis yog peb tuaj yeem siv ntau qhov ntsuas xws li litmus ntawv lossis pH ntawv. Hauv pH nplai, cov kua qaub yog sawv cev los ntawm 1-6. Cov kua qaub nrog pH 1 tau hais tias muaj zog heev, thiab raws li tus nqi pH nce, acidity poob qis. Ntxiv mus, acids tig xiav litmus rau liab.
Txhua cov kua qaub tuaj yeem muab faib ua ob hom organic acids thiab inorganic acids nyob ntawm lawv cov qauv. Hydrochloric acid yog ib qho uas nquag siv muaj zog inorganic acid. Nws tseem hu ua mineral acid, thiab nws yog muab los ntawm cov pob zeb hauv av. Inorganic acids tso protons thaum yaj hauv dej.
Hydrogen Chloride
Hydrogen chloride yog nyob rau hauv daim ntawv gaseous, thiab nws muaj cov mis molecular ntawm HCl. Nws yog ib qho roj ntawm chav tsev kub thiab tsis muaj xim. Qhov no yog diatomic molecule, thiab molar loj ntawm nws yog 36.46 g mol−1. Nws muaj ntxhiab tsw.
Cov chlorine atom thiab hydrogen atom ntawm cov molecule txuas nrog covalent daim ntawv cog lus. Cov nyiaj no yog polar vim ntau electronegativity ntawm chlorine piv rau hydrogen. Hydrogen chloride yog soluble hauv dej heev. Hauv qab no yog cov tshuaj tiv thaiv dissociation ntawm HCl hauv aqueous nruab nrab.
HCl +H2O → H3O+ + Cl –
Hydrogen chloride yog tsim los ntawm hydrogen gas thiab chlorine gas. Cov khoom tsim hydrogen chloride yog siv los tsim hydrochloric acid.
Y Hydrochloric Acid
Hydrochloric acid, uas tseem txhais tau tias yog HCl, yog cov ntxhia acid, uas muaj zog heev thiab muaj zog heev. Qhov no yog cov kua uas tsis muaj xim, uas tsis yog-flammable. Nws yog ruaj khov, tab sis nkag tau yooj yim nrog cov hauv paus thiab hlau. Nws muaj lub peev xwm los ionize thiab pub tsuas yog ib qho proton xwb. Txij li nws yog cov kua qaub muaj zog, cov kua qaub dissociation tas li ntawm HCl yog qhov loj heev.
HCl yog siv rau hauv cov chiv, roj hmab, textile thiab dye manufacturing industries. Tsis tas li ntawd, nws yog cov kua qaub uas siv dav hauv cov chaw soj nstuam rau lub hauv paus titrations, los yog muab cov kua qaub tawm, lossis ua kom tsis zoo rau cov kev daws teeb meem, thiab lwm yam.
Qhov txawv ntawm Hydrogen Chloride thiab Hydrochloric Acid yog dab tsi?
