The color of liquid Palladium Chloride, in a large bottle is a light brownish to sort of a flesh color. However, when in a small amount, as shown in next image it is yellowish with a tint of orange. When completely dry it becomes reddish brown.

10x – Palladium (liquid) chloride (yellowish color) in neck of a polypropylene pipette, that is about to be dispensed onto a glass slide.

10x – The liquid Palladium chloride that was in the pipette is now placed on glass slide and gently heated to dry, producing this reddish-brown color, without a distinct crystal pattern.

When Palladium chloride is heated it has a rather pleasant and somewhat distinctive sweet odor that is not likely forgotten.

40x – A magnified view of the previous image attempting to better illustrate color of the dried palladium chloride.

40x – Another magnified view of dried palladium chloride on same slide as in previous image.

10x – Powdered DMG (Dimethylgycine) placed in the liquid palladium chloride on a glass slide, that is waiting for a couple drops of pure grain alcohol to complete the test procedure.
Normally DMG is premixed (supersaturated) with pure grain alcohol and then applied to a chloride solution (devoid of nitrates) suspected of containing palladium. However, I prefer to place a little bit of DMG powder into the solution, stir and then add the alcohol.
I wait awhile for most of the alcohol to vaporize naturally then carefully add heat from a cigarette lighter flame to underside of glass slide. If I get too hasty the cigarette lighter flame will ignite the alcohol.

10x – This image illustrates what happens when the DMG is mixed with pure grain alcohol (190 proof). DMG with alcohol is one of, if not the best method of confirming the presence of dissolved Palladium in hydrochloric acid.
This reaction is not quick and only becomes apparent when near or completely dry.

40x – A magnified view of a portion of the preceding image for better visual clarification.

10x – A single crystal of potassium Iodide (KI) was inserted into a drop of palladium chloride, which produced this immediate precipitation.

40x – The previous image was completely dried by slowly heating the glass slide, which better illustrates this black KI precipitant that even concentrated nitric acid will not dissolve.

30x – Oxalic Acid crystal insertion into a single drop of Palladium chloride solution that created no immediate precipitation, indicating that Oxalic acid is not a reagent to use to confirm the presence of Pd in a chloride solution. However, this image does show what Oxalic acid shows this crystalline formation when solution was forced dried.

35x – Potassium dichromate does not produce a precipitant and only colors the solution orange, thus is not a suitable reagent for determining the presence of Pd. Nevertheless, when the solution was forced to dry the reddish crystal structure was interesting enough to present.

30x – This image is the result of placing a single crystal of potassium dichromate (K2Cr2O7) in a drop of concentrated HCl and forced to dry. The purpose of this image is merely to illustrate the significant difference between this and the previous image.
