Principles of Reactivity: Electron Transfer Reactions. Chapter 20. Electron Transfer Reactions. In order to produce electricity, the electron transfer between substances must be carried out in an apparatus that allows the electrons to be transferred through an electrical circuit.
ALL REDOX REACTIONS MUST BE BALANCED FOR BOTH MASS AND CHARGE!
Al(s) + H+(aq) Al3+(aq) + H2(g)
Write balanced half-reactions and the balanced net ionic equation. Identify the oxidizing agent, the reducing agent, the substance oxidized, and the substance reduced.
MnO4-(aq) + Fe2+(aq) Mn2+(aq) + Fe3+(aq)
Cu(s)ICu2+(aq, 1.0M)IIAg+(aq, 1.0M)IAg(s)
Standard Potentials are measured under these conditions; Eocell
Zn(s) + 2Ag+(aq) Zn2+(aq) + 2Ag(s)
Assuming standard conditions, identify the half-reactions that occur at the anode and the cathode and calculate a potential for the cell.
