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.
