As th name of the table indicates, all the Half cell in the table are Reduction Half cell. To create an Oxidation Half cell, you reverse the Half cell reaction and the volt sign changes (from positive to negative or visa versa). This is how the two half cell or the overall Redox reaction are created. Now, the combined voltage of the reactants and products produce a combined difference that is called the Cell potential, Ecell. This is the Free Energy Difference between the reactants and the products so it is the Energy that "makes the reaction go" or in a Redox reaction, it is the energy difference that moves the electrons. |

In both Electrolysis and Electroplating, electrical energy is being converted into chemical energy. Therefore, it is the reverse of Voltaic/Daniel Cell and will NOT be spontaneous and will have a negative Cell potential. There difference between Electrolysis and Electroplating is that Electrolysis separates compounds into their elements whereas Electroplating reduces metal ions into element metals (usually as solids). The most common application of Electrolysis is making hydrogen and oxygen gas from water. The most common application of Electroplating is plating metals such as in jewelry making or copper deposit to produce "motherboards in electronic device like computers. |

There is a table of these Half cells and associated volts called Standard Reduction Potential Table, (see link below to see table),
