What occurs during a redox reaction.

As the reaction proceeds the blue disappears and a copper colored solid appears on the bottom of the container. As the above video shows, placing zinc metal into the copper(II) solution results in a spontaneous redox reaction (\(\Delta G <0\)), and if we placed the copper metal into the zinc solution no reaction would occur (\(\Delta G >0\)).Since zinc is losing electrons during this reaction, it is being oxidized. The sulfur is gaining electrons, so it is being reduced. Each of these processes can be shown in a separate equation called a half-reaction. A half-reaction is an equation that shows either the oxidation or the reduction reaction that occurs during a redox reaction.We will also look at how electrical power can make nonspontaneous redox reactions occur.
