CH 101 Lecture 11: Electron Transfer and Electrochemistry
Document Summary
Explain the electron transfer process and define the terms associated with redox reactions. Explain how balanced chemical equations are written for electron transfer reactions. Show how to calculate standard cell potentials sand how to use them to predict whether a redox process is extensive. Final exam review : monday 11/27, 6-9 pm in dabney hall room 222. Characterized by electron transfer between an electron donor and an electron acceptor. Redox reaction : a reduction and an oxidation are occurring in a reaction. Goal : from any (balanced) chemical equation, identify: oxidation states, number of electrons transferred, half reactions; oxidant(oxidizing agent) and reductant(reducing agent) Transfer leads to -: increase in oxidation # of some element in balanced chemical equation (oxidation, decrease in oxidation # of some element in balanced chemical equation (reduction) The electric charge an element appears to have when electrons are counted by the following.
