Strong reducing and oxidizing agents among the following , respectively, are

Options

  1. ACe 3 + and Ce 4 +
  2. BCe 4 + and Tb 4 +
  3. CCe 4 + and Eu 2 +
  4. DEu 2 + and Ce 4 +

Correct answer

D. Eu 2 + and Ce 4 +

Step-by-step solution

E Ce 4 + / Ce 3 + = + 1 . 74   V Lanthanoids have + 3 oxidation state as stable oxidation state. Hence, in their + 4 oxidation state, they act as an oxidising agents and + 2 oxidation state, they act as reducing agents.
