The strongest and weakest reducing agents are should be given from given set of agents. Concept introduction: Standard reduction potential: The reducing tendencies of the chemical species are measured at 1M concentration and 1atm pressures for all gases are called standard reduction potential. In electrochemistry standard reduction potential for Hydrogen is assumed to zero then respect with this, the standard reduction potential for others species are measured and these measured standard reduction potential are arranged in the increasing ordered, this is known as standard reduction potential table.

Definition Definition Study of chemical reactions that result in the production of electrical energy. Electrochemistry focuses particularly on how chemical energy is converted into electrical energy and vice-versa. This energy is used in various kinds of cells, batteries, and appliances. Most electrochemical reactions involve oxidation and reduction.

a) Under acidic conditions, H3PO4 can be reduced into H3PO3 directly (-0.28V), or via the
formation and reduction of H4P206 (-0.93/+0.38V). Calculate the values of AG's for both
processes; comment.
