草酸（英語： Oxalic acid ），也称酢浆草酸，IUPAC 系統名為乙二酸，化學式為HO 2 C–CO 2 H。它是最简单的二羧酸。它是一种白色结晶固体，溶于水中形成无色溶液。它的名字来源于早期研究人员从酢浆草属的开花植物中分离，通常为酢浆草。它天然存在于许多食物 ...

Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula HO−C (=O)−C (=O)−OH, also written as (COOH)2 or (CO2H)2 or H2C2O4. It is the simplest dicarboxylic acid. It is a white crystalline solid that forms a colorless solution in water.

草酸是一种有机物，化学式为H₂C₂O₄，是生物体的一种代谢产物，中强酸，广泛分布于植物、动物和真菌体中，并在不同的生命体中发挥不同的功能。 研究发现百多种植物富含草酸，尤以 菠菜 、 苋菜 、 甜菜 、 马齿苋 、芋头、甘薯和大黄等植物中含量最高，由于草酸可降低矿质元素的生物利用率，在人体中容易与钙离子形成草酸钙导致肾结石，所以草酸往往被认为是一种矿质元素吸收利用的 拮抗物。 其 酸酐 为 三氧化二碳。 溶于水、乙醇，不溶于苯、氯仿。 无色单斜片状或棱 …
