General Description

Oxalic acid is a naturally occurring organic compound with the chemical formula C2H2O4. It is a white, crystalline solid that is highly soluble in water. Oxalic acid can be found in various plants, such as rhubarb, spinach, and beets, as well as in some animals.

One of the notable properties of oxalic acid is its strong acidity. It is classified as a dicarboxylic acid due to its two carboxyl groups (COOH), which give it its acidic nature. Oxalic acid is considered a relatively strong acid in terms of its dissociation in water.
