    There is no Cu^3+(aq) ion....

    The few compounds in which copper(III) exists usually involve other metals in insoluble oxides. (https://en.wikipedia.org/wiki/Copper#Copper(III)_a...

    Copper III is already a cation. An atom of metallic copper loses 3 electrons to become copper III.

    Cu -----> Cu3+ because it LOSES 3 electrons.

    As the ion is attracted to the cathode (-) it is called a cation (NOT caption)
