Nyob rau hauv Brønsted–Lowry txhais ntawm acids thiab bases, an acid yog proton (H⁺) pub, thiab lub hauv paus yog proton txais. Thaum Brønsted-Lowry acid poob ib qho proton, lub hauv paus conjugate yog tsim. Ib yam li ntawd, thaum Brønsted–Lowry puag tau txais ib qho proton, ib qho conjugate acid yog tsim.
Puas yog cov kua qaub txhais tias yog cov neeg pub dawb?
Acids yog Proton Donors thiab Bases yog Proton txais Rau qhov tshuaj tiv thaiv kom muaj kev sib npaug, kev hloov ntawm electrons yuav tsum tshwm sim. Cov kua qaub yuav muab ib qho hluav taws xob tawm thiab lub hauv paus yuav tau txais cov hluav taws xob.
Puas yog acids electron pub lossis txais?
Brønsted-Lowry daim duab ntawm cov kua qaub thiab cov hauv paus ua cov neeg pub dawb thiab cov neeg txais tsis yog tib lub ntsiab lus hauv kev siv ntau. Lub ntsiab txhais dav dua yog muab los ntawm Lewis txoj kev xav ntawm cov kua qaub thiab cov hauv paus, uas Lewis acid yog ib qho hluav taws xob-pair txaisthiab Lewis puag yog ib qho khoom siv hluav taws xob.
Leej twg yog cov neeg pub dawb?
(Science: chemistry) Ib acid, ib qho susbstance uas pub protons nyob rau hauv ib qho acid-base txo cov tshuaj tiv thaiv.
Vim li cas cov kua qaub pub protons?
Hauv chemistry, Brønsted–Lowry txoj kev xav, uas tseem hu ua proton txoj kev xav ntawm cov kua qaub thiab cov hauv paus, hais tias txhua qhov sib xyaw uas tuaj yeem hloov cov proton mus rau lwm qhov sib xyaw yog cov kua qaub, thiab cov compound uas txais cov proton yog lub hauv paus. … Yog li, los ntawm qhov kev xav no, protons pub dawb los ntawm cov kua qaub thiab txais los ntawm lub hauv paus.

Puas yog polyprotic acids tsis muaj zog acids?
Defining Polyprotic Weak Acids H 2 A is a diprotic acid vim nws tuaj yeem pub 2 protons. H 2A yog cov kua qaub uas tsis muaj zog vim nws tsis ua kom tiav (ionise), uas yog, daim ntawv molecular ntawm cov kua qaub nyob rau hauv qhov sib npaug nrog cov ions uas tsim los ntawm nws ib nrab dissociation.
Puas yog cov amino acids tuaj ntawm?
Qhov zoo tshaj plaws ntawm cov amino acids tseem ceeb yog tsiaj proteins xws li nqaij, qe thiab nqaij qaib. Thaum koj noj cov protein, nws tau tawg mus rau hauv cov amino acids, uas yog siv los pab koj lub cev nrog ntau yam txheej txheem xws li tsim cov leeg nqaij thiab tswj kev tiv thaiv kab mob (2).
Phau Vajlugkub puas txwv tsis pub pub khoom nruab nrog cev?

Puas yog nucleic acids hydrophobic?
DNA yog tsim los ntawm ob txoj hlua, muaj cov suab thaj molecules thiab phosphate pawg. … Qhov chaw ib puag ncig yog li hydrophilic, thaum lub DNA molecules ' nitrogen bases yog hydrophobic, thawb tawm cov dej nyob ib puag ncig. YPuas yog nucleotide hydrophobic lossis hydrophilic?
