  1. Strengths of Ox. & Red. Agents

  2. Strengths of Ox. & Red. Agents gain • Strongoxidizingagentsarespeciesthat_______electrons very easily, whereas strong reducing agents are species that _______ electrons very easily! • Strong oxidizing agents have_______electronegativities, whereas strong reducing agents have _______ electronegativities! lose high low O2 EN = 3.5 strong oxidizing agent ger lon OA Ca strong reducing agent leo gon RA EN = 1.0

  3. Strengths of Ox. & Red. Agents • Strong oxidizing agents are usually pure nonmetals, whereas strong reducing agents are usually pure metals (see Reference Table J)! Pure Metals Pure Nonmetals Strongest Reducing Agents F20 Strongest Oxidizing Agents Li0 gain electrons lose electrons Weakest Oxidizing Agents I20 Weakest Reducing Agents Au0

  4. Strengths of Ox. & Red. Agents Pure Metals – lose electrons Get off me, Elroy! Ruby, you’re SUCH a loser. Rb0 Rb1+ e1- We’re basically stuck with each other Curt. You’re not going anywhere, Elvira! Cu0 e1-

  5. Strengths of Ox. & Red. Agents Pure Nonmetals – gain electrons I want you NOW! You’re all MINE! Clark, you’re SO possessive. 2 Cl1- Cl20 2e1- Ida, are you even interested in me? Only a little, Eric. I20 e1-

  6. Strengths of Ox. & Red. Agents • Metallic ions are oxidizing agents whereas nonmetallic ions are reducing agents (see Reference Table J)! Metallic Ions Nonmetallic Ions Weakest Oxidizing Agents F1- Weakest Reducing Agents Li1+ lose electrons gain electrons Strongest Reducing Agents I1- Strongest Oxidizing Agents Au3+

  7. Strengths of Ox. & Red. Agents Metallic Ions – gain electrons Lily, where’s the magic gone? I’m just NOT very interested, Eddie. Li1+ e1- Mmmm, I love those things SO much, I just can’t have one! Aurelia, you’re SUCH a pig. Au3+ Au0 3e1-

  8. Strengths of Ox. & Red. Agents Nonmetallic Ions – lose electrons I’m NEVER letting you go, Ella. We’re together forever, Felix. xoxoxo F1- e1- I want you Esther, but I CAN let you go. So long Ian. I1- e1-

  9. Strengths of Ox. & Red. Agents Ex.1) Which of the following species is the strongest oxidizing agent using Reference Table J? (1) F2 (2) I2 (3) Cl2 (4) Br2 • Oxidizing agents are used to kill bacteria in pools, drinking water, and open wounds such as cuts. • Hydrogen peroxide produces O2 gas. • Tincture of iodine is a solution of iodine (I2) and alcohol. • Municipalities chlorinate drinking water with chlorine compounds. • People put chlorine and/or bromine compounds in their swimming pools. • Chlorine bleach is used as a disinfectant.

  10. Strengths of Ox. & Red. Agents Ex.2) Which of the following species is the strongest oxidizing agent using electronegativity values? (1) F2 (2) I2 (3) Cl2 (4) Br2 Ex.3) Which of the following species is the strongest reducing agent using Reference Table J? (1) Ca (2) Zn (3) H2 (4) Au Ex.4) Which of the following species can most easily be oxidized? (1) Ag (2) Cu (3) Au (4) Pb Ex.5) Which of the following species can most easily be reduced to the pure metal? (1) Cu2+ (2) Sn2+ (3) Fe2+ (4) Al3+

  11. Strengths of Ox. & Red. Agents Ex.6) Which metallic substance can mosteasilybereduced by hydrogen gas? (1) AuCl3 (3) AlCl3 (2) CuCl2 (4) AgCl Ex.7) According to Reference Table J, which reaction occurs more easily? Au → Au3+ + 3 e-OR Ag → Ag1+ + e- _________________________ Pb2+ + 2 e- → Pb OR Zn2+ + 2 e- → Zn _________________________ Ag → Ag1+ + e- Pb2+ + 2 e- → Pb
