                Which of the two reactions in Blue Printing is an oxidation-reduction reaction? What is the oxidizing agent and the reducing agent? 
Fe^3+ + C204^-2 (oxalate) -> Fe^2+ + CO3
Fe^2+ + Fe (CN)6^-2 -> Fe3[Fe(CN)6]2
Can the second reaction occur in the absence of light? Explain please!

    In 1, Fe^+3 changes from +3 to +2 and each C changes from +3 to +4. The second reaction is not a redox rxn.
Oxidation is the loss of electrons.
Reduction is the gain of electrons.
