The anhydrous salt is prepared by heating loose palladium sponge (contained in a porcelain boat set in a glass tube) to a dull red heat in a stream of
Cl2. According to Krustinsons, the decomposition pressure of PdCl2 reaches 1 atm. at 738°C. By dissolving finely divided Pd in conc. HCl
through which Cl2 is bubbled, one obtains a solution in which both H2PdCl4 and H2PdCl6 can be detected. Concentrating the solution also yields a
residue of PdCl2.

PdCl2 Solution for the Detection of CO

Winkler gives the following method for preparing this solution. Pure Pd (0.2 g.) is dissolved with gentle heating in about 10 ml. of aqua regia. The
solution Is evaporated to dryness in a 50-ml. porcelain dish placed on a steam bath. The residue is dissolved in 10 ml. of 20% hydrochloric acid and
the solution is again evaporated to dryness; this last procedure is repeated three times. The resulting residue, which is now completely nitrate-free,
is mixed with 2 g. of KBr and dissolved (gentle heating) in 10 ml. of 1 N HCl. After dilution to about 150 ml. with water, a few particles of pumice
and 1 ml. of alcohol are added to the solution. which is then boiled for about 10 minutes in an Erlenmeyer flask in order to reduce any Pd (M) not
decomposed during the drying to Pd (H) and to drive off the excess alcohol. After cooling. 2.5 g. of CH3COONa . 3 H2O is dissolved In the liquid. The
solution Is filtered through a small wad of cotton wool and diluted to 200 ml. with the water used for washing the cotton wool. The clear, reddish-
brown liquid, which contains 0.1% palladium. is stable when stored in a flask provided with a ground-glass stopper. To be on the safe side, It Is best
to filter the solution before use; It should be stored In the dark.
