An oxidation half-reaction is characterized by electrons appearing on the product side. The oxidation of aluminum for instance would be represented thusly: Al(s) → Al3+ + 3e- (1) An reduction half-reaction is characterized by electrons appearing on the reactant side. The reduction of ferrous iron for instance would be represented thusly: Fe2+ + 2e...

Sn^2+ is a stronger oxidizing agent than Fe^2+ because it has a larger (more positive) reduction potential. Determine a metal that could be oxidized with a Sn^2+ solution but not a Fe^2+ solution. Build an electrochemical cell that could harness this spontaneous redox reaction to generate electricity. You may either draw a picture or describe the cell using cell notation.

Chem 1212 Lab Report on electrochemistry
Electrochemistry When electrons transfer between reaction components in a redox reaction, we can harness the motion of the electrons to create a potential. Electrochemistry revolves around the separation of the two half-reactions in a redox reaction and establishing two different electrodes. This might involve physically separating the half-reactions or including a separator, such as a semi-permeable membrane or plastic dividers. With the reactions separated, the electrons will need to flow through the wire connecting...
