PALLADIUM (Pd)

 

MATERIAL OVERVIEW

Characteristics: Silver-white, ductile metal which does not tarnish in air. It is the least noble (most reactive) of the platinum group. Absorbs up to 800 times its own volume of hydrogen. Attacked by hot, concentrated nitric acid and boiling sulfuric acid. Soluble in aqua regia and fused alkalies. Insoluble in organic acids. Good electrical conductor. Nontoxic; noncombustible, except as dust.
