Decide whether or not each metal dissolves in 1 molL−1 HNO3. Standard Electrode Potentials at 25 ∘C Reduction Half-Reaction E∘(V)

NO3−(aq)+4H+(aq)+3e− →NO(g)+2H2O 0.96

Cu2+(aq)+2e− →Cu(s) 0.34

Au3+(aq)+3e− →Au(s) 1.50

Pb2+(s)+2e− →Pb(s) -0.13

Write a balanced redox reaction showing what happens when Pb dissolves.
