'''Asam oksalat''' adalah senyawa kimia yang memiliki rumus H<sub>2</sub>C<sub>2</sub>O<sub>4</sub> dengan nama sistematis asam etanadioat. Asam dikarboksilat paling sederhana ini biasa digambarkan dengan rumus HOOC-COOH.
Merupakan [[asam organik]] yang relatif kuat, 10.000 kali lebih kuat daripada [[asam asetat]].
Di-[[anion]]nya, dikenal sebagai oksalat, juga agen pereduktor.
Baris 51 ⟶ 95:
Banyak ion logam yang membentuk endapan tak larut dengan asam oksalat, contoh terbaik adalah kalsium oksalat(CaOOC-COOCa), penyusun utama jenis [[batu ginjal]] yang sering ditemukan.
