HOOCCOOH2H2O

HOOCCOOH2H2O represents oxalic acid dihydrate. Oxalic acid, with the chemical formula (COOH)2, is a simple dicarboxylic acid. In its dihydrate form, it incorporates two molecules of water into its crystal structure, hence the formula HOOCCOOH2H2O. This compound is a white crystalline solid at room temperature. It is soluble in water and ethanol. Oxalic acid is a naturally occurring substance found in many plants, such as rhubarb and spinach. It is also produced metabolically by some organisms. Industrially, it can be synthesized through various methods, including the oxidation of carbohydrates or ethylene glycol. Oxalic acid dihydrate is a moderately strong acid. It is commonly used as a cleaning agent, particularly for rust and stains, due to its ability to chelate iron. It also finds applications in the textile industry as a mordant and in various chemical synthesis processes. Due to its acidic and chelating properties, it can be irritating to skin and mucous membranes and is toxic if ingested. Proper handling and safety precautions are necessary when working with oxalic acid dihydrate.
