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.

What is the reaction mechanism of the Fe and HCl reaction?
In the reaction between iron (Fe) and hydrochloric acid (HCl), the Fe reacts with the HCl to form iron chloride (FeCl2) and hydrogen gas (H2). This reaction is a single displacement reaction, where the Fe displaces the hydrogen in the HCl to form the products.
What half -reaction equation represents the reduction of iron 2 ion?
The half-reaction equation representing the reduction of iron (II) ion (Fe^2+) is: Fe^2+ + 2e^- -> Fe
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.
What is the oxidizing agent in the reaction Fe AgNO3 Fe(NO3)3 Ag?
In this reaction, Ag^+ is the oxidizing agent. It undergoes reduction by accepting electrons from Fe to form silver metal, while Fe gets oxidized to Fe^3+ in the process.
