Question
Okay now can you read my introduction for me please...
INTRODUCTION:
This report discusses an experiment to study the percent mass of iron determined by the concentration of a colored iron solution from the absorbance of the spectrometer. This lab is designed to determine the content of iron in cereal; often food products list iron and many of the other contents ingredients as a percentage. The box of Kix cereal has the iron content as 43%.

Phenanthroline (C12H8N2) was added to the colorless prepared solution and a phenanthroline-iron (II) complex was formed. The absorbance of the resulting colored solution was measured on the spectrophotometer and the percent iron was read from a graph that had been prepared previously from standard solutions of iron. 4The Fe (II) concentration was determined spectrophotometrically with 1, lO-phenanthroline, this equation for the iron phenanthroline: 2Fe3+ + 2NH2OH + 2OH- ----> 2Fe2+ + N2 + 4H2O
