Question

question 5 of 30 which redox reaction would most likely occur if zinc and copper metal were added to a solution that contained zinc and copper ions? click for a reduction potential chart a. cu²⁺ + zn → cu + zn²⁺ b. cu²⁺ + zn²⁺ → cu + zn c. cu + zn → cu²⁺ + zn²⁺ d. cu + zn²⁺ → cu²⁺ + zn

Explanation:

Step1: Recall activity series

Metals higher in activity series can displace lower ones from their salts. Zinc is more reactive than copper.

Step2: Analyze redox reaction

Zinc will lose electrons (oxidize) and copper ions will gain electrons (reduce).

Step3: Write the reaction

The reaction is $\mathrm{Cu^{2 +}+Zn
ightarrow Cu + Zn^{2+}}$.

Answer:

A. $\mathrm{Cu^{2 +}+Zn
ightarrow Cu + Zn^{2+}}$
