Oxalic acid is colorless, crystalline solid that is highly soluble in water. Oxalic acid exists in many plants, particularly in vegetables like spinach, rhubarb, and cacao. It is also synthesized industrially through the oxidation of carbohydrates or hydrocarbons.
Oxalic acid is a dicarboxylic acid, meaning it has two carboxylic acid groups. It is a relatively strong acid in terms of its chemical properties. It is also a reducing agent and can form coordination compounds with metal ions.
