Spectrophotometric Determination of Iron for Highschools

Spectrophotometric Determination of Iron for Highschools

curve (absorbance versus concentration) is constructed for iron +II and the concentration of the unknown iron sample is determined. Theory Colorimetric analysis is based on the change in the intensity of the colour of a solution with variations in concentration. Colorimetric methods represent the simplest form of absorption analysis.
