The TPTZ-Fe reaction in antioxidants tests the ability of various fruits, nuts, and food items to reduce Fe 3+ to Fe 2+ which binds TPTZ (2,4,6-tri(2-pyridyl)-1,3,5-triazine (TPTZ) very tightly with an extinction coefficient equal to 21,600 at 593 nm. The binding of Fe 2+ to this ligand creates a very intense navy blue color and this absorbance can be measured to test the amount of iron reduced.

Is an oxidation half-reaction A. Fe2 plus Fe3 plus plus e- B. Fe3 plus plus e- Fe2 plus C. Fe(s) Fe(l) D. Fe plus 2e- Fe2 plus?
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
What is the oxidation half reaction for Fe(s) 2HCl(aq) FeCl2(aq) H2g?
The oxidation half-reaction is: Fe => Fe+3 + 3e-, and the reduction half-reaction is: F2 + 2e- => 2 F-1. For a complete equation, the oxidation half-reaction as written must be multiplied by 2 and added to the reduction half-reaction as written multiplied by 3 to result in an overall reaction of 2 Fe + 3 F2 = 2 FeF3.
