i need help on writing an experimental flow chart for a procedure where i was only given the general guidelines.

i need help on writing an experimental flow chart for a procedure where i was only given the general guidelines.

i will be given an unknown solution containing either CO(NO3)2, Cu(NO3)2, or Ni(NO3)2 at an unknown concentration between 0.05 M and 1.0 M. My goal is to determine the metal ion identity in the solution and to determine the concentration in M of the metal ion in the solution.

I need to use a spectrometer and utilize the Beer-Lambert Relationship. I need to make a calibration curve of absorbance vs. concentration.
