Question

What is the oxidizing agent in the redox reaction represented by the following cell notation? Ni(s) | Ni2+(aq) || Ag+(aq) | Ag(s)

Answer 1

Answer:

Silver.

Explanation:

Hello,

In this case, for the redox reaction:

$Ni^0(s)+Ag^+(aq)\rightarrow Ni^{2+}+Ag^0(s)$

We can see the nickel is being oxidized as its oxidation state increases from 0 to 2+ whereas the oxidation state of silver decreases from +1 to 0, it means that the oxidizing agent is silver and the reducing agent is nickel.

Best regards.
