Application
Even when dry, palladium(II) chloride is able to rapidly stain stainless steel. Thus, palladium(II) chloride solutions are sometimes used to test for the corrosion-resistance of stainless steel
Palladium(II) chloride is sometimes used in carbon monoxide detectors.
Palladium(II) chloride is used in the Wacker process for production of aldehydes and ketones from alkenes.
Palladium(II) chloride can also be used for the cosmetic tattooing of leukomas in the cornea.
