Identify oxidant and reductant, respectively, in the following reaction: Zn (s) + Cu ²⁺(aq) Zn ²⁺(aq) + Cu (s)
Options
- AZn , Cu ²⁺
- BCu , Zn ²⁺
- CCu ²⁺ , Zn
- DZn ²⁺ , Cu ²⁺
Correct answer
C. Cu ²⁺ , Zn
Step-by-step solution
In the given reaction, the oxidation state of Zn changes from 0 to +2 . Since it loses electrons and undergoes oxidation, Zn acts as a reductant (reducing agent). The oxidation state of Cu changes from +2 to 0 . Since Cu ²⁺ gains electrons and undergoes reduction, Cu ²⁺ acts as an oxidant (oxidizing agent). Therefore, the oxidant and reductant are Cu ²⁺ and Zn , respectively. Answer: Cu ²⁺ , Zn
