Qhov sib txawv tseem ceeb ntawm carbonic acid thiab carbolic acid yog carbonic acid yog carboxylic acid compound, whereas carbolic acid yog cawv.
Txawm hais tias cov ntsiab lus carbonic acid thiab carbolic acid suab zoo ib yam, lawv hais txog ob hom tshuaj sib txawv. Carbonic acid yog H2CO3 hos carbolic acid yog C6H5 OH. Lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv.
Carbonic Acid yog dab tsi?
Carbonic acid yog H2CO3 Qee zaum, peb muab lub npe no rau cov tshuaj uas muaj carbon dioxide yaj hauv dej lossis dej carbonated. Nws yog vim cov dej carbonated muaj me me ntawm H 2 CO 3 Ntxiv mus, qhov no yog cov kua qaub tsis muaj zog, thiab nws tuaj yeem tsim tau ob hom ntsev. raws li carbonates thiab bicarbonates. Cov molar loj ntawm cov compound yog 62.024 g / mol.
Thaum cov pa roj carbon dioxide yaj hauv dej, qhov sib xyaw no nkag mus rau qhov sib npaug ntawm carbon dioxide thiab carbonic acid. Lub equilibrium yog raws li nram no;
CO2 + H2O ⟷ H2CO 3
Daim duab 01: Cov qauv ntawm Carbonic Acid
Yog tias peb ntxiv cov roj carbonic acid ntau dhau rau hauv lub hauv paus, nws muab bicarbonate. Tab sis, yog hais tias muaj ntau tshaj ntawm lub hauv paus, ces carbonic acid nyhav muab carbonated ntsev. Ntau precisely, carbonic acid yog ib tug carboxylic acid compound uas muaj ob pawg hydroxyl substituents txuas rau carbonyl carbon. Ntxiv mus, nws yog polyprotic acid, uas muaj peev xwm pub dawb protons. Nws muaj ob tug tshem tau protons; Yog li, nws yog tshwj xeeb diprotic.
YCarbolic Acid yog dab tsi?
YCarbolic acid yog C
6H5OH. Nws yog ib qho organic compound. Lub npe nrov ntawm cov tshuaj no yog "phenol". Nws muaj lub nplhaib benzene nrog ib qho ntawm nws cov hydrogen atoms hloov nrog ib pawg hydroxyl. Nws tshwm sim raws li ib tug dawb crystalline, volatile khoom. Cov acidity ntawm cov tshuaj no yog me me, tab sis peb yuav tsum tau saib xyuas thaum tuav vim yog cov tshuaj kub hnyiab uas nws yuav ua rau. Cov molar loj ntawm cov compound yog 94.13 g / mol. Nws muaj ntxhiab tsw qab vim nws yog ib qho tshuaj tsw qab.
Daim duab 02: Cov qauv ntawm Carbolic Acid
Ntxiv mus, nws yog cov kua qaub tsis muaj zog, thiab hauv cov tshuaj aqueous, nws muaj nyob hauv qhov sib npaug nrog phenolate anions. Lub pH ntawm cov dej aqueous no tuaj yeem nyob ntawm 8 txog 12. Vim lub resonance stabilization ntawm cov compound no, phenol yog acidic ntau dua li cov aliphatic tsis muaj zog acids.
Qhov txawv ntawm Carbonic Acid thiab Carbolic Acid yog dab tsi?
Carbolic acid yog H2CO3 thaum carbolic acid yog C6H 5OH. Qhov sib txawv tseem ceeb ntawm carbonic acid thiab carbolic acid yog carbonic acid yog carboxylic acid compound, whereas carbolic acid yog cawv.
Ntxiv mus, qhov sib txawv ntxiv ntawm carbonic acid thiab carbolic acid yog tias txawm tias ob qho tib si tsis muaj zog acids, carbolic acid yog acidic ntau dua carbonic acid vim tias cov nyhuv resonance stabilization hauv cov compound.
Hauv qab infographic qhia ntau qhov kev sib piv ntsig txog qhov sib txawv ntawm carbonic acid thiab carbolic acid.
Summary - Carbonic Acid vs Carbolic Acid
Carbolic acid yog H2CO3 thaum carbolic acid yog C6H 5OH. Qhov sib txawv tseem ceeb ntawm carbonic acid thiab carbolic acid yog carbonic acid yog carboxylic acid compound, whereas carbolic acid yog cawv.
