Unformatted text preview: Jessica Gaboriault 10/30/07 Lab Report 4 Lab Partner: Melissa Mayer Introduction : In this lab, we are working with iron in Total cereal which is fortified with Fe in the form of very small metallic iron crystals. When you eat the cereal, the iron crystals dissolve in stomach acids (primarily HCl) to form Fe 2+ . The Fe 2+ is oxidized to form Fe 3+ . The purpose of this lab is to compare your experimental conditions to the biological situation. Procedure : See pages 34-37 in the lab manual for the procedure. We followed the procedure the same way as it was presented in the lab manual. Data and Observations : - Weighed 10.00 grams of cereal- Weight of dry 400 mL beaker is 109.26 g- Weight of dry beaker plus cereal 119.25 g- * This loss of 0.01 gram could be from loss of some iron when transferring the crushed cereal from the bag to the beaker....
