Objectives

• Analyze solutions of porphine and either Al₂(SO₄)₃, Fe₂(SO₄)₃ FeSO₄, or Na₂SO₄ in HPLC H₂O.

Absorbance of Solutions of 1.89 μM Porphine and Varied Concentration of Salt in HPLC H₂O

• The concentrations of salt in a total solution volume of x mL, with porphine concentration of 1.89 μM were as follows:
  • 1 mM, 2 mM, 5 mM, and 10 mM Al₂(SO₄)₃
  • 1 mM, 2 mM, 5 mM, and 10 mM Fe₂(SO₄)₃
  • 1 mM, 2 mM, 5 mM, and 10 mM FeSO₄
  • 1 mM, 2 mM, 5 mM, and 10 mM Na₂SO₄

• There were 16 solutions in total.
