Question

1) Which of the following is the weakest oxidizing agent?

Question options: a) Fe3+(aq) b) ClO2(g) c) I2(s) d) Fe(s) e)H2O2(aq)

2)A galvanic cell consists of one half-cell that contains Ag(s) and Ag+(aq), and one half-cell that contains Cu(s) and Cu2+(aq). What species are produced at the electrodes under standard conditions?

Ag+(aq) + e- ? Ag(s) E° = +0.80 V

Cu2+(aq) + 2 e- ? Cu(s) E° = +0.34 V

Question 6 options:

Cu(s) is formed at the cathode, and Ag+(aq) is formed at the anode.

Cu2+(aq) is formed at the cathode, and Cu(s) is formed at the anode.

Ag(aq) is formed at the cathode and, Cu(s) is formed at the anode.

Ag(s) is formed at the cathode, and Cu2+(aq) is formed at the anode.

Cu(s) is formed at the cathode, and Ag+(aq) is formed at the anode.

Cu2+(aq) is formed at the cathode, and Cu(s) is formed at the anode.

Ag(aq) is formed at the cathode and, Cu(s) is formed at the anode.

Ag(s) is formed at the cathode, and Cu2+(aq) is formed at the anode.

Explanation / Answer

1. d) Fe (s) is weakest oxidizing agent because reduction of Fe into its anion is highly unfavourable.

2 Ag(s) is formed at the cathode, and Cu2+(aq) is formed at the anode.

Because Ag has higher reduction potential thats why Ag+ is reduced to solid Ag at cathode and Cu(s) is oxidized to Cu+2 (aq) at anode.
