7. Use the following standard reduction potentials to determine which species is the strongest reducing agent.
2 H+(aq) + 2 e– → H2(g); 0.00 V
K+(aq) + e– → K(s); –2.93 V
F2(g) + 2 e– → 2 F–(aq); 2.87 V
Al3+(aq) + 3 e– → Al(s); –1.66 V
Pb2+(aq) + 2 e– → Pb(s); –0.13 V

Answer:


8. Write a balanced net ionic equation for the overall reaction represented by the following cell notation.
Al(s) | Al3+(aq) || Cl2(g) | Cl–(aq) | Pt(s)
