PPT-Redox equations

Starter What is redox Redox what Oxidation and reduction happen at the same time There is no net gain or loss of electrons e You cant just create them or destroy them Example the . 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. Such reductio Titration. OF bleach . Due Today: . 1. Redox Titration of Bleach Pre-Lab. 2. . Copper Reduction Formal Lab Report. Homework:. 1. Redox . Titration . Short Report. 2. Gravimetric Analysis of Phosphorus Pre-Lab. Definition. If oxidation occurs, then reduction must also occur. Any chemical process in which elements undergo a change in oxidation number is a . Redox reaction. Example. 2Na + Cl. 2. . → 2Na. 14.1 Redox Equations (Review). 14.2 Electrode Potentials and the Electrochemical Series. 14.3 Predicting the Direction of Redox Reactions. 14.4 Uses for Electrochemical Cells. 14.1 Redox Equations.
