Hi,

This question has to do with half reactions and balancing for the cell. There are a lot of other similar questions, so was there something specific about this one that was confusing? Are you maybe confused about the cell diagram?

Hope this was helpful

14.17 (a) Write balanced half-reactions for the redox reaction of an acidified solution of potassium permanganate and iron(II) chloride. (b) Write the balanced equation for the cell reaction and devise a galvanic cell to study the reaction (write its cell diagram)

I would look up the redox reactions in appendix 2b and use those to write the redox reaction, then create a cell based off that.

The half-rxns are given in the back of the book. Potassium and chloride are not part of the half-rxns because they're part of the solutions. Basically for this type of problem you just balance and add the half-reactions.

to start the cell diagram it helps to label each side as anode or cathode

Th toolboxes on 563 and 575 are helpful!
