Q44
4. How are electrochemical couples written? Oxidant/Reductant or Reductant/Oxidant? Define
the terms reductant and oxidant.
Note: This is a follow-up on Question 43 above.
Consider the following chemical reaction:
2FeBr3 (aq) + 3Zn (s) → 3ZnBr2 (aq) + 2Fe (s)
Is this a redox reaction? And if so, what is being oxidized in the reaction?
Group of answer choices
This is a redox reaction. Both the iron (Fe) and the zinc (Zn) are being oxidized.
This is not a redox reaction.
This is a redox reaction. The iron (Fe) is being oxidized.
This is a redox reaction. The zinc (Zn) is being oxidized.
This is a redox reaction. The bromine (Br) is being oxidized.
