Product information
Oxalic acid
Oxalic acid is a relatively strong, dibasic carboxylic acid and the simplest dicarboxylic acid molecule. It occurs naturally in many plants, including spinach, rhubarb, and sorrel, often in the form of its salts, the oxalates. In the human body, excessive intake can promote the formation of kidney stones, as oxalic acid forms sparingly soluble salts with calcium. Therefore, in high concentration, it must be classified as harmful to health or even toxic. The acid typically exists as the dihydrate, a white, crystalline solid. Its strong reducing properties make it a useful reagent in chemistry and industry.
Oxalic acid has diverse applications due to its chemical properties. It is frequently used in cleaning and restoration, particularly for removing rust stains and lightening wood. In the textile industry, it serves as a bleaching agent and a mordant in dyeing. Furthermore, oxalic acid is an important substance for controlling the Varroa mite in beekeeping. In analytical chemistry, it is used as a primary standard for the titration of bases (alkalis). Finally, in the chemical industry, it serves as a starting material for the production of other chemicals.
