Oxidation-Reduction (Redox) Reactions 1. Redox: Introduction Electrons (e - ) are transferred from one compound to another –e - -donors (lose electrons)
Electrode Potentials In a redox reaction, electrons are transferred between the reacting chemicals. Zinc reacts with aqueous copper (II) ions in a redox.
The Daniell cell was invented by John Daniell in 1836.
Galvanic (= voltaic) Cells Redox reactions which occur spontaneously are called galvanic reactions. Zn will dissolve in a solution of copper(II) sulfate.
