Palladium By Micro Photo Films

 Palladium:-Palladium (II) chloride:




Palladium (II) chloride: Palladium (II) chloride is prepared by the
careful evaporation of a solution of hydrogen tetrachloropalla date(II)
in hydrochloric acid, preferably in a rotary evaporator.




Palladium (II) chloride: Palladium (II) chloride is used in plating
baths. Pellets or monoliths of oxidation catalysts are either immersed
in an aqueous solution of palladium (II) chloride (impregnation
technique) or sprayed with a solution of this chemical.





Other uses for palladium (II) chloride include photography, toning
solutions, electroplating parts of clocks and watches, detecting carbon
monoxide leaks in buried gas pipes, manufacture of indelible ink and
preparation of metal for use as a catalyst (Budavari et al., 1996;
Olden, 1997). Different purity grades of palladium (II) chloride ranging
from 99% to 99.999% are available for chemical or medical use.
