Recall the mnemonics LEO GER.
The ease to remove an electron from an element is also related to cell potential.
• Larger (↑) E° → stronger oxidizing agent
Gather the reduction potentials.
Sn2+(aq) + 2e- → Sn(s) Ered = -0.14V
Cl2(g) + 2e- → 2 Cl-(aq) Ered = 1.36 V
Ag+(aq) + e- → Ag(s) Ered = 0.80 V
Cu2+(aq) + e- → Cu(s) Ered = 0.34 V
K+(aq) + e- → K(s) Ered = -2.92 V
Rank the following in increasing ability as oxidizing agents.
Sn2+(aq) Cl2(g) Ag+(aq) Cu2+(aq) K+(aq)
