If a nail made of elemental iron [Fe(s)] is placed in an aqueous solution of a soluble palladium(II) salt [Pd2+ (aq)], the nail will gradually disappear as the iron enters the solution as Fe3+ (aq) and palladium metal [Pd(s)] forms.
a. Is this a redox equation?
b. Balance and show the net ionic equation that describes this reaction.
