Show answer
Palladium will not react with dilute sulfuric acid because it is below hydrogen in the reactivity series.
Also accept: No reaction because palladium is less reactive than hydrogen.; Palladium is below hydrogen so it cannot displace hydrogen.
Common mistakes: Predicting a reaction because palladium is a metal.

Marking points
M1 · 1 mark · Correctly predicts no reaction between palladium and dilute sulfuric acid.
A1 · 1 mark · Gives an appropriate reason: palladium is below hydrogen so cannot displace hydrogen from the acid.
Worked solution
Palladium is below hydrogen in the reactivity series, so it is not reactive enough to displace hydrogen from dilute sulfuric acid. Therefore, no reaction will occur.
