PPT-Chapter 14 REDOX AND POTENTIOMETRIC TITRATIONS

REDOX AND POTENTIOMETRIC TITRATIONS WE WILL LEARN FROM THIS CHAPTER Balancing redox reactions Calculating the reaction equilibrium constant from standard potentials Calculating . Databases treating redox reactions must include either . O. 2. (. aq. ). or . H. 2. (. aq. ). in the list of Basis Species. . This species is the database’s “redox pivot”.. O. 2. (. aq. ) is the . Redox potentials are used to infer the direction and free energy cost of reactions involving electron transfer, one of the most ubiquitous and important types of biochemical reactions.
