Infobox references

Cerium(III) oxalate (cerous oxalate) is the inorganic cerium salt of oxalic acid. It is a white crystalline solid with the chemical formula of Ce2(C2O4)3. It can be obtained by the reaction of oxalic acid with cerium(III) chloride.

## Uses

Cerium(III) oxalate is used as an antiemetic.[2][3] It has been identified as part of the invisible ink that was used by Stasi operatives during the Cold War.[4]

## Toxicity

Cerium(III) oxalate irritates skin and mucous membranes, and is a strong irritant to eyes. If it gets into the eyes, there is a danger of severe eye injury.[5]

Cerium salts increase the blood coagulation rate, and exposure to cerium salts can cause sensitivity to heat.

Oxalates are corrosive to tissue and are powerful irritants. They have a caustic effect on the linings of the digestive tracts and can cause kidney damage.
