Question

Which of the following set of ions act as oxidizing agents?

• A. \(Ce^{4+}\) and \(Tb^{4+}\)
• B. \(La^{3+}\) and \(Lu^{3+}\)
• C. \(Eu^{2+}\) and \(Yb^{2+}\)
• D. \(Eu^{2+}\) and \(Tb^{4+}\)

Hint:

In Lanthanoids: \[ +4 \rightarrow +3 \] means reduction, so the ion acts as an oxidizing agent. \[ +2 \rightarrow +3 \] means oxidation, so the ion acts as a reducing agent.

Answer 1

The Correct Option is A
