Title: A tricky cell notation?
Post by: Bublik on June 22, 2013, 10:51:53 AM

The question is to draw a cell notation for the following reaction in a galvanic cell.

4Fe²⁺(aq) + O₂(g) + 4H⁺(aq)  :rarrow: 4Fe³⁺(aq) + 2H₂O(l)

This is how I wrote it:

{Pt(s)|Fe²⁺(aq)(1M), Fe³⁺(aq)(1M)||H₂O(l)|H⁺(aq)(1M)|O₂(g)|Pt(s)}

Is this correct? I was unsure of what to do with the H₂O since I've never seen it in a cell notation before. But I included it because it makes the whole flow of electrons from left to right make sense.

Any help would be very appreciated!
