Ib qho anion nrog cov qauv dav dav (RCO2)-, uas yog tsim thaum cov hydrogen txuas nrog Cov pawg carboxyl ntawm cov carboxylic acid raug tshem tawm.
Yuav ua li cas yog carboxylate ion tsim?
Carboxylate ions tuaj yeem tsim by deprotonation ntawm carboxylic acids . Cov kua qaub no feem ntau muaj pKa ntawm tsawg dua 5, txhais tau tias lawv tuaj yeem deprotonated los ntawm ntau lub hauv paus, xws li sodium hydroxide lossis sodium bicarbonate.
YPuas yog carboxylate ion ib anion?
Qhia: Ib qho carboxylate ion raug suav tias yog lub hauv paus ntawm carboxylic acid. Cov organic tebchaw uas muaj cov pab pawg carboxyl, piv txwv li, pawg - COOH raws li pab pawg ua haujlwm hu ua carboxylic acids. Lub carboxylate ion yog anion nrog tsuas yog tus nqi tsis zoo
Koj npe li cas carboxylate anion?
Tau lub npe carboxylate ions coj lub npe ntawm cov kua qaub, poob "ic" thiab ntxiv "ate"ion. Lub npe zoo ion mus ua ntej ib yam li hauv cov tshuaj inorganic (xws li sodium chloride, potassium fluoride) txawm tias qhov zoo ion tau pom ntawm sab xis ntawm carboxylate, raws li nws nyob hauv cov qauv saum toj no.
YPob carboxylate ions hauv dej?
Dej-soluble carboxylic acids ionize me ntsis hauv dej rau tsim cov kua qaub me ntsis. Lawv cov kev daws teeb meem aqueous nthuav tawm cov yam ntxwv ntawm cov kua qaub, xws li hloov litmus ntawm xiav mus rau liab. Cov anion tsim thaum carboxylic acid dissociates hu ua carboxylate anion (RCOO-).
