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.

Is this a redox equation?

Balance and show the net ionic equation that describes this reaction.

Yes, its a redox reaction.

Explanation:

It is obviously a redox reaction.

Oxidation: Fe (s)=Fe3+(aq)+3e-(aq)

Reduction: Pd2+(aq)+2e-=Pd(s)

Fe os oxidized as its oxidation state increased from 0 to +3

Pd is reduced as ots oxidation state decreased from +2 to 0.

Add 2x oxidation + 3x Reduction and cancel electrons to get ionic equation:

2Fe (s) + 3Pd2 + (aq) = 2Fe3+(aq)+3Pd (s)

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
