Question

Cu2+ + 2e- -> Cu Oxidation reaction
Cu -> Cu2+ + 2e Reduction Reaction

Do I have these right, or are they backwards?

Answer 1

backwards.
The first one is ADDING electrons.
The second one is LOSING electrons.

Answer 2

Acronym ...
O = Oxidation
I = is
L = Loss (of electrons) A => A^+ + e^-

R = Reduction
I = is
G = Gain (of electrons) B + e^- => B^-

Answer 3

Another one is LEO the lion goes Grr.
LEO is loss electrons oxidation
