Answer:
Redox" is a word coined from two chemical terms:
• reduction = species gain electrons
•oxidation = species lose electrons
Redox reactions involve electron transfers; if one species gains electrons, another species (or more than one species) must lose electrons. For example, the redox reaction in which zinc displaces copper in an aqueous solution of copper sulfate:
CuSO4(aq) + Zn(s) → ZnSO4(aq) + Cu(s)
In terms of electrons:
Cu2+(aq) + 2e- → Cu(s)
Reduction of Cu2+(aq)
and
Zn(s) → Zn2+(aq) + 2e-
