Oxalic acid yog cov organic sib xyaw nrog cov mis C2H2O4. Nws yog cov xim tsis muaj xim crystalline uas tsim cov xim tsis muaj xim hauv dej. Nws cov mis ua kua yog HOOCCOOH, xav txog nws kev faib tawm raws li qhov yooj yim dicarboxylic acid. Nws cov kua qaub muaj zog ntau dua li ntawm acetic acid. Oxalic acid yog txo tus neeg sawv cev thiab nws cov hauv paus conjugate, lub npe hu ua oxalate (C 2O2−4), yog chelating tus neeg sawv cev rau hlau cations. Feem ntau, oxalic acid tshwm sim raws li dihydrate nrog cov mis C2H2O4 · 2H2O. Kev noj ntau dhau ntawm oxalic acid lossis kev sib cuag tawv nqaij ntev tuaj yeem ua rau txaus ntshai.
