Dicarbonsäure, also known as oxalic acid, is a dicarboxylic acid with the chemical formula H2C2O4. It is a white crystalline solid that is soluble in water and has a tart taste. Oxalic acid is naturally occurring in many plants, including rhubarb, spinach, and sorrel, and is also found in certain animals, such as the ox, from which it derives its name. It is widely used in various industries, including the textile, leather, and metal industries, as a bleaching agent and in the production of other chemicals. Oxalic acid is also used in the food industry as a preservative and in the pharmaceutical industry for its antiseptic properties. It is considered a weak acid and can form salts called oxalates. Oxalic acid is toxic if ingested in large amounts, and its handling requires appropriate safety measures.
