Solution: Use data from the table below to determine which metal does not dissolve in hydrochloric acid (HCl).
Zn2+(aq)+2e → Zn(s)E˚ = –0.76 V
Cd2+(aq)+2e → Cd(s)E˚ = –0.40 V
Cu2+(aq)+2e → Cu(s)E˚ = –0.34 V
Cu+(aq)+e → Cu(s)E˚ = –0.52 V
Fe2+(aq)+2e → Fe(s)E˚ = –0.45 V
Fe3+(aq)+3e → Fe(s)E˚ = –0.036 V
