About Oxalic Acid Crystals ACS Grade

Oxalic Acid Crystals Lab Grade is a crystalline white solid at room temperature that forms a colorless solution with water. It is a naturally occurring chemical in the body, and is found extensively in fruits and vegetables, especially leafy greens.

Oxalic Acid is used in high school and college settings for analytical work such as titrations, and in industrial settings it is used for cleaning or bleaching, especially for the removal of rust (iron complexing agent). Its utility in rust removal agents is due to its forming a stable, water-soluble salt with ferric iron, ferrioxalate ion. Oxalic acid is used for extractive metallurgy. It is an important reagent in lanthanide chemistry

The ACS Grade is generally equivalent to the reagent grade and is acceptable for use in analytical applications and research laboratories.
