Yog tias npe ntawm cov ion xaus hauv "-ate," hloov nws mus rau "-ic" thaum naming lub kua qaub.

Tib neeg kuj nug, txoj cai rau npe cov kua qaub yog dab tsi?

Cov kua qaub muaj npe raws li lawv cov anion - cov ion txuas nrog hydrogen.

Kuj hu ua ethanoic acid, acetic acid yog cov kua xim tsis muaj xim uas ua lub luag haujlwm tseem ceeb hauv txhua txoj kev lom neeg. Nws cov qauv tshuaj yog qee zaum sau ua CH3COV or CH3CO2H hais txog nws lub koom haum atomic.

Ntxiv mus, dab tsi yog hom kev hu ua Oxyacid?

Ib oxyacid nrog ob lub pa oxygen tsawg dua li cov (hauv paus) ic acid yog lub npe los ntawm kev sau ntawv hypo-, ces lub hauv paus ntawm lub npe rau lub caij uas tsis yog hydrogen thiab oxygen, ces -ous, thiab ces acid. Yog li, HClO, yog hypochlorous acid.

Puas yog HCl yog cation lossis anion?

HCl , uas muaj cov anion chloride, hu ua hydrochloric acid . HCN, uas muaj cov anion cyanide, hu ua hydrocyanic acid. Cov cai rau naming Oxyacids ( anion muaj cov pa oxygen): Vim tias tag nrho cov acids muaj tib yam cation , H+, peb tsis tas yuav sau npe cation.
