Experiment E10 Phosphate Analysis in Soil and Water
Spectroscopy is the science of the analysis of light. The proportions of specific wavelengths of light absorbed by a sample depend on the nature of the absorbing molecules and their concentration in the sample. In this experiment you will use this idea to determine the phosphate (PO43-) concentration in garden soil and creek water samples.
