Identify oxidant and reductant, respectively, in the following reaction:
$\text{Zn}(s) + \text{Cu}^{2+}(aq) \longrightarrow \text{Zn}^{2+}(aq) + \text{Cu}(s)$

Question

Identify oxidant and reductant, respectively, in the following reaction: Zn(s) + Cu^ 2+ (aq) Zn^ 2+ (aq) + Cu(s)

Quantrex Academy · Accepted Answer

Correct answer: C. Cu^ 2+ , Zn

In the given reaction, the oxidation state of

\text{Zn}

changes from

0

to

+2

. Since it loses electrons and undergoes oxidation,

\text{Zn}

acts as a reductant (reducing agent).

The oxidation state of

\text{Cu}

changes from

+2

to

0

. Since

\text{Cu}^{2+}

gains electrons and undergoes reduction,

\text{Cu}^{2+}

acts as an oxidant (oxidizing agent).

Therefore, the oxidant and reductant are

\text{Cu}^{2+}

and

\text{Zn}

, respectively.

Answer:

\text{Cu}^{2+}

,

\text{Zn}

Identify oxidant and reductant, respectively, in the following...
