14.17 - HW

Postby Andrew Nguyen 2I » Tue Feb 20, 2018 12:02 am

Since potassium permanganate and iron(II) chloride are asked to be used, how are we supposed to know which element in each compound is the electrode element; like for potassium permanganate - how do we know that potassium is not at the electrode, and also for iron(II) chloride.

Also, after we find out that only MnO4- is involved, how are we supposed to know that it forms Mn2+ ?

You can find these half reactions in Appendix 2B.
