The reaction of zinc with copper (ll) ions in aqueous solution can be represented as follows: Cu 2+(aq) +Zn (s) → Cu(s) + Zn 2+(aq).Which of the following is the most complete description of this reaction?
A. Cpper (ll) ions are being reduced B. Zinc is being oxidized. C. Copper (ll) ions and zinc are being reduced D. copper (ll) ions and zinc are being oxidized E. copper(ll) ions are being reduced and zinc oxidized
Correct Answer: E
Explanation
Copper (II) ions (Cu²⁺) are gaining electrons to form copper metal (Cu), which is a reduction process.
Zinc (Zn) is losing electrons to form zinc ions (Zn²⁺), which is an oxidation process.
