We can only guess what C6H8O6 is.
Looks like there are several possible processes here. Can you start by listing things that can be oxidized? Reduced?
If you have confirmed Fe2+ was produced you probably did some experiment - can you describe it? Every bit of information can be important.
Sorry, I am a new poster here. I have tried setting the equation to C
6H
8O
6 + H
2O
2 + K
3Fe(CN)
6 + Fe
0 + NaCl
Fe
2++ + 2e- + C
6H
8O
6 + H
2O
2 + K
3Fe(CN)
6 + NaCl, but that didn't seem correct because the ascorbic acid and the hydrogen peroxide should have reacted with the iron. The only other possible equation would be C
6H
8O
6 + H
2O
2 + K
3Fe(CN)
6 + Fe
0 + NaCl
Fe+2 + Na2O + HCl + 2e-, but that also probably isn't correct because that would just be a combination of the results of Fe
0 + NaCl + H
2O
2 and Fe
0 + NaCl + C
6H
8O
6.
I am fairly sure but not 100% positive that the Fe was oxidized.
C

6 is Ascorbic Acid. What happened during the lab procedure is that we added 1 drop of K
3Fe(CN)
6 (an indicator that turns blue upon the presence of Fe
2+) and 9 drops of salt water (Yes, we know that the measurement is fairly inaccurate but my teacher did not give us anything more precise to work with). Then, we added an iron nail into this solution, before adding 2 drops of hydrogen peroxide and what I can only assume is 1 teaspoon of ascorbic acid (again, my teacher wasn't very exact on measurements this lab for whatever reason). We waited for 20 minutes while watching the indicator (K
3Fe(CN)
6) turn blue, indicating the presence of Fe
2+. And that's pretty much the entire lab procedure.
Please tell me if I am missing additional information.
