Aim: To Find and test the Iron content in different food sources INTRODUCTION: A Redox titration was used in order to perform this experiment. Reduction/oxidation (redox) process occurs when electrons are transferred from a donor species (the reducing agent) to another acceptor species (the oxidizing agent).

The Iron-Carbon Diagram There are two iron-carbon equilibrium diagrams: - stable iron-graphite Fe-Gr - metastable iron-cementite Fe-Fe3C The stable condition usually takes a very long time to develop. The metastable diagram is of more interest. Fe3C iron carbide called cementite because it is hard. Following phases exist on Fe-Fe3C diagram: - liquid solution of iron and carbon (L) - ferrite ( ) – an interstitial solid solution of carbon in Fe (bcc). At room temperature ferrite is ductile but
