Question

C152-02 Class Practice Chapter 21 Practice 3 Will permanganate ions, MnO, oxidize iron (II) ions to iron (II) ions, or will iron (II) ions oxidize manganese(II) ions (Mn2") to permanganate ions in acidic solution? (hint: use the table of standard reduction potentials to determine which has more oxidizing power) 2re Mnoy tFe Fe +7 at Mnay +FeO FeMn nodos wort Ine Will niric acid, HNOs, oxidize arsenous acid, HASO), in acidic solution? The reduction product of HNO, is NO in this reaction.

dont mind the work on the first one

Answer 1

- Iron having atomic number 26 has more oxidizing power than Manganese, therefore iron(III) will oxidize permagnate ions in acidic solution.

- Nitric acid is a strong oxidizing agent, and it will oxidize H3AsO3 in acidic solution.
