Raws li qib ntawm ionization ntawm cov kua qaub nyob rau hauv cov kua aqueous, cov kua qaub tau muab faib ua cov kua qaub uas muaj zog thiab tsis muaj zog acids. Feem ntau, cov kua qaub muaj zog raug suav tias yog ionize tag nrho hauv cov tshuaj aqueous- piv txwv suav nrog hydrochloric acid thiab nitric acid-thaum cov acids tsis muaj zog ionize ib feem hauv cov tshuaj aqueous, xws li acetic acid thiab carbonic acid.
Muaj zog acids: Perchloric acid, hydroiodic acid, sulfuric acid, hydrobromic acid, hydrochloric acid, nitric acid, iodic acid, thiab lwm yam.
Muaj zog acids: Oxalic acid (ethanedioic acid), sulfurous acid, phosphoric acid, pyruvic acid, nitrous acid.
Cov kua qaub tsis muaj zog: Carbonic acid (uas qee tus xav txog cov kua qaub qis), citric acid, hydrofluoric acid, malic acid, gluconic acid, formic acid, lactic acid, benzoic acid, acrylic acid, acetic acid, propionic acid, stearic acid, hydrosulfuric acid, hypochlorous acid, boric acid.
Hais txog oxyacids: ib daim ntawv uas feem ntau raug xaiv los ua "acid" (xws li chloric acid); Lwm cov oxyacids muaj npe raws li seb lub xeev oxidation ntawm lub hauv paus acid- tsim cov khoom siab dua lossis qis dua li cov qauv acid, lossis seb lawv puas muaj peroxide -O-O- qauv. Piv txwv li: chloric acid (HClO₃, qhov twg lub xeev oxidation ntawm chlorine yog +5); perchloric acid (HClO₄, oxidation xeev +7); chlorous acid (HClO₂, oxidation xeev +3); thiab hypochlorous acid (HClO, oxidation xeev +1). Ib yam li ntawd, cov tebchaw xws li HSO₅ thiab H₂S₂O₈, uas muaj -O-O- bonds, yog hu ua peroxymonosulfuric acid thiab peroxydisulfuric acid, raws li. Cov kua qaub tsim los ntawm kev sib xyaw ua ke ntawm ob qho yooj yim oxyacid molecules nrog kev tshem tawm ntawm ib lub molecule ntawm dej yog hu ua "pyroacid" (los yog "condensed acid"); Tsis tas li ntawd, cov lus hais ua ntej "di-" (los yog "meta-") yuav raug siv nyob rau hauv nomenclature. Cov pab pawg ua haujlwm tau tsim thaum ib qho yooj yim oxyacid poob tag nrho nws cov hydroxyl pawg hu ua "acyl pawg" (tshwj xeeb, ib qho "oxyacyl pawg"); Piv txwv li, -SO₂ yog hu ua sulfonyl pawg, thiab CrO₂Cl₂ yog hu ua chromyl chloride. Yog hais tias cov tshuaj formula ntawm ib tug oxyacid yog sau nyob rau hauv daim ntawv dav dav MOₙ(OH)ₘ (qhov twg M sawv cev rau ib tug hlau los yog nonmetal), tus txheeb ze lub zog ntawm cov oxyacids muaj peev xwm kwv yees raws li tus nqi ntawm *n*: yog *n*=0, nws yog ib tug tsis muaj zog acid (xws li, boric acid, H₃BO).
