HCl yog a muaj zog acid vim nws dissociates yuav luag tag. Los ntawm qhov sib txawv, cov kua qaub tsis muaj zog zoo li acetic acid (CH 3 COOH) tsis cuam tshuam zoo hauv dej - ntau H+ ions nyob twj ywm hauv lub molecule.
Vim li cas yog vim li cas hydrochloric acid thiaj li muaj zog acid?
HCl yog cov kua qaub muaj zog vim nws muaj ntau cov hydrogen ions whereas acetic acid muaj tsawg cov hydrogen ions yog li nws cov kua qaub tsis muaj zog, nws tuaj yeem sib txawv los ntawm kev hloov tus lej. ntawm hydrogen ions hauv lawv.
6 lub zog acids yog dab tsi?
Rau MCAT, koj yuav tsum paub tias cov kua qaub muaj zog yog cov kua qaub uas sib cais tag nrho hauv cov tshuaj. Muaj rau ntawm lawv uas koj yuav tsum tau cim rau MCAT. Lawv yog H2SO4 (los yog sulfuric acid), HI (hydrologic acid), HBr (hydrobromic acid), HNO3 (nitric acid), HCl (hydrochloric acid) thiab HClO4 (perchloric acid)
2 cov kua qaub tsis muaj zog yog dab tsi?
Qee yam piv txwv ntawm cov acids tsis muaj zog muaj npe hauv qab no
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH3COOH)
- Benzoic acid (chemical formula: C6H5COOH)
- Oxalic acid (cov tshuaj formula: C2H2O4)
- Hydrofluoric acid (cov tshuaj formula: HF)
- Nitrous acid (tshuaj formula: HNO2)
7 lub zog tsis muaj zog yog dab tsi?
Tam sim no cia peb tham txog qee cov piv txwv tsis muaj zog acid:
- Acetic acid (CH3COOH)
- Formic acid (HCOOH)
- Oxalic acid (C2H2O4)
- YHydrofluoric acid (HF)
- Nitrous acid (HNO2)
- Sulfurous acid (H2SO3)
- Phosphoric acid (H3PO4)
- Benzoic acid (C6H5COOH)

HBR Puas yog cov kua qaub muaj zog?
HCl, HBr, thiab HI yog tag nrho cov acids muaj zog , hos HF yog cov kua qaub tsis muaj zog. Cov kua qaub zog acid lub zog txhais lus ntawm cov kua qaub muaj zog Lub zog ntawm cov kua qaub yog hais txog rau qhov yooj yim uas cov kua qaub poob ib qho proton Cov kua qaub muaj zog ionizes tag nrho hauv cov tshuaj aqueous los ntawm poob ib qho proton, raws li qhov sib npaug hauv qab no:
Puas yog cov kua qaub tsis muaj zog ionize?
A qaub qaub tsis muaj zog yog ib qho acid uas ionizes me ntsis hauv cov tshuaj aqueous … A 0.10 M tov ntawm acetic acid tsuas yog kwv yees li 1.3% ionized, txhais tau hais tias qhov sib npaug sib npaug zoo siab. cov reactants. Cov kua qaub tsis muaj zog, zoo li cov kua qaub muaj zog, ionize kom tawm los H + ion thiab lub hauv paus conjugate.
Puas yog cov kua qaub tsis muaj zog?
Buffers. Ib qho tsis yog cov tshuaj aqueous muaj cov kua qaub tsis muaj zogthiab nws lub hauv paus conjugate lossis lub hauv paus tsis muaj zog thiab nws cov kua qaub sib txuas. Lub pH tsis hloov pauv me me thaum me me ntawm cov kua qaub uas muaj zog lossis cov hauv paus ntxiv rau nws .
Qhov twg yog qhov chaw uas cov kua qaub ncaug rov qab mus rau cov ntshav?
Lim cov kua dej lim dej ces txav mus rau qhov loj lymphatic ducts lymphatic ducts Ib lub qog ntshav yog lub lymphatic hlab ntsha loj uas tso cov qog ntshav mus rau hauv ib qho ntawm cov hlab ntsha subclavianMuaj ob lub qog ntshav hauv lub cev - txoj cai lymphatic duct thiab lub thoracic duct.
Dab tsi ua rau cov kua qaub ua kua qaub?
Ib tug kua qaub yog ib yam khoom uas pub hydrogen ions Vim li no, thaum cov kua qaub yaj hauv dej, qhov sib npaug ntawm hydrogen ions thiab hydroxide ions hydroxide ions Hydroxide yog diatomic anion nrog tshuaj formula OH - Nws muaj cov pa oxygen thiab hydrogen atom tuav ua ke los ntawm ib qho kev sib cog lus, thiab nqa cov hluav taws xob tsis zoo.
