With yesterdays data in disagreement with Bertin's experiment, today was used to determine the reasons for these discrepancies. We began by adding surplus amounts of Magnesium to the solution in an attempt to see some form of NCP falling out of solution. This was to no avail as the solutions continually tested a similar concentration of NCP from UV vis spectrometer testing. The reasons why this experiment is not consistent remains unknown. Perhaps the Magnesium was incorrectly concentrated. The experiment may need to be performed again.
