Potassium oxalate monohydrate is a source of oxalate ion. Oxalic acid (and formic acid) is readily oxidized and combine with calcium, iron, sodium, magnesium, or potassium to form less soluble salts called oxalates. Oxalic acid and oxalates are useful as reducing agents for photography, bleaching, and rust removal. Oxalate is widely used as a purifying agent, precipitation of rare-earth metals in processing operations, as a bleaching agent in textile and wood processing, and as a reagent in analytical chemistry for the determination of calcium and other heavy metals.
