Question

The equation below represents the titration that will he completed in Experiment 20B. It is sometimes called n redox titration because an oxidation reaction occurs. What is the reducing agent? The oxidizing reagent? Explain your answers. 16 H^+ + 5 C_2 O_4^2- + 2 Mn O^-_4 rightarrow 10 CO_2 + 2 Mn^2+ + 8 H_2 O In solution, the ferrioxalate complex undergoes photoreduction. The complex absorbs a photon of light and decomposes to form Fe(C_2 O_4}^2-_2 and CO_2. What are the initial and final oxidation states of the iron during this process?

Explanation / Answer

2. oxidising agent = MnO4 -

   reducing agent = C2O4^2-

3. iron ox.state changes from +3 to +2 state.
