# Redox question watch

1. Here's the question and I don't know what to do:

Iron in food, in the form of reacts with ascorbic acid (vitamin C), to form dehydroascrobic acid,

(a) Write an ionic half equation to show the conversion of the ascorbic acid to dehydroascorbic acid in aqueous solution

(b) In the other ionic half-equation is converted to . Deduce the overall equation for the reaction between and
2. a) in the first question C6H8O6 is losing 2 H^+ ions to become C6H6O6. So your half equation should be showing C6H8O6 and 2 electrons going to C6H6O6 and 2H^+.
b) Fe^3^+ becomes Fe^2^+ by gaining 1 electron. Times this by 2 to get an equal charge on both half equations:
2Fe^3^+ + C6H8O6 goes to 2Fe^2^+ + C6H6O6.

All that needs to be done is balance the 2 equations so that the overall loss or gain of electrons is 0 and add the 2 equations together

not quite..
C6H8O6 --> C6H6O6 + 2H+ + 2e
4. My error. Sorry!
