Problem: You are titrating a 50.0 mL solution of an unknown concentration of chloride ions (Cl⁻) with 0.100 M silver nitrate (AgNO₃) using a silver/silver chloride electrode. The standard electrode potential for the silver/silver chloride electrode is E∘=0.222 V. Calculate the potential of the solution at the following points: 1. Before adding any AgNO₃. 2. After adding 10.0 mL of AgNO₃. 3. At the equivalence point. 4. After adding excess AgNO₃ (e.g., 60.0 mL). Solve: 1. You are titrating a 50.0 mL solution of 0.100 M iodide ions (I−) with 0.100 M lead(II) nitrate (Pb(NO₃)₂) using a lead electrode. The standard electrode potential for the lead electrode is E∘=−0.126 V. Calculate the potential of the solution at the following points: 4.5 marks a) Before adding any lead(II) nitrate. b) After adding 25.0 mL of lead(II) nitrate. c) At the equivalence point. d) After adding excess lead(II) nitrate (e.g., 75.0 mL). 2. You are titrating a 50.0 mL solution of 0.050 M hydrogen peroxide (H2O2) with 0.100 M potassium permanganate (KMnO4) using a platinum electrode. The standard electrode potential for the platinum electrode is E∘=0 V. Calculate the potential of the solution at the following points: 4.5 marks a) Before adding any potassium permanganate. b) After adding 25.0 mL of potassium permanganate. c) At the equivalence point. d) After adding excess potassium permanganate (e.g., 75.0 mL).
