Chemistry - Blue Printing Experiment
posted by Bam .
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.
Which one is the oxidizing agent and the reduction agent?
Can the second reaction occur in the absence of light? Thank you!
