Ib organic acid yog ib organic kev sib xyaw nrog acidic khoom. Feem ntau organic acids yog cov carboxylic kua qaub Nws acidity yog txuam nrog lawv cov carboxyl pawg -COOH. Tus txheeb ze stability ntawm lub conjugate puag ntawm lub kua qaub txiav txim nws acidity.
Cov lus nug tseem yog, koj tuaj yeem qhia tau li cas yog tias cov kua qaub yog cov organic?
Ib tug zoo txoj kev txheeb xyuas seb puas yog koj tab tom saib ib qho organic acid yog nrhiav carboxylic kua qaub pab pawg ua haujlwm, RCOOH. Feem ntau, organic acids muaj pab pawg no. Tsis tas li ntawd, nco ntsoov tias yuav tsum yog organic , nws yuav tsum muaj cov pa roj carbon atom tam sim no hauv nws cov qauv.
Ib sab saum toj no, yog NaH lub hauv paus lossis kua qaub? Acid-Base Character Piv txwv li, hauv sodium hydride (NaH) the hydrogen muaj -1 nqi yog li nws tsis yog acid tab sis nws yog qhov tseeb.
Kuj paub, dab tsi yog acids thiab bases hauv chemistry?
Hauv chemistry , acids thiab bases tau raug txhais txawv los ntawm peb pawg ntawm kev xav. Ib qho yog Arrhenius txhais, uas tig los ntawm lub tswv yim ntawd kua qaub yog cov khoom uas ionize (so tawm) nyob rau hauv ib tug aqueous tov los tsim hydrogen (H+) ions thaum hauv paus tsim hydroxide (OH-) ions hauv kev daws.
Puas yog NaCl yog cov kua qaub lossis lub hauv paus?
NaCl yog tsim los ntawm cov tshuaj tiv thaiv ntawm HCl thiab NaOH. Ob leeg muaj zog kua qaub thiab hauv paus . Thaum muaj zog kua qaub thiab muaj zog puag react ua ke lub resultant yog ntsev thiab dej. Yog li ntawd NaCl yog ntsev.

Dab tsi yog qhov txawv ntawm cov chemistry thiab organic chemistry?
Organic chemistry yog suav tias yog ib qho kev qhia ntawm chemistry. Thaum lub sij hawm lub kaus dav dav 'chemistry' yog kev txhawj xeeb nrog kev sib xyaw thiab kev hloov pauv ntawm txhua yam teeb meem, cov khoom siv tshuaj lom neeg tsuas yog txwv rau kev kawm ntawm cov organic tebchaw xwb
Koj puas ntxiv cov kua qaub rau hauv lub hauv paus lossis lub hauv paus rau cov kua qaub?
Ntxiv cov kua qaub ua kom cov concentration ntawm H3O + ions hauv cov tshuaj. Ntxiv ib lub hauv paus txo cov concentration ntawm H3O + ions hauv cov tshuaj. Cov kua qaub thiab lub hauv paus zoo li cov tshuaj tiv thaiv. Yog hais tias lub hauv paus yog ntxiv rau cov kua qaub, cov tshuaj yuav tsis acidic thiab txav mus rau nruab nrab ntawm pH nplai
Dab tsi yog qhov txawv ntawm cov kua qaub thiab cov hauv paus ntawm pH nplai?
Distinguishing ntawm acids thiab bases. Keydifference: Acids thiab bases yog ob hom tshuaj corrosive. Txhua yam khoom uas muaj pH tus nqi nruab nrab ntawm 0 txog 7 yog suav tias yog acidic, qhov apH tus nqi ntawm 7 txog 14 yog lub hauv paus. Cov kua qaub yog cov ioniccompounds uas sib cais hauv dej los tsim cov hydrogen ion (H +)
Dab tsi yog qee cov kua qaub hauv tsev thiab cov hauv paus?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
Cov piv txwv ntawm tsev neeg cov kua qaub thiab cov hauv paus yog dab tsi?
Daim ntawv teev cov tsev Bases & Acids Baking Soda. Baking soda yog lub npe nrov rau sodium bicarbonate, paub tshuaj raws li NaHCO3. Diluted Soaps. Tsev neeg Ammonia. Tsev Neeg Vinegar. Citric Acid
