Objectives

• Make stock solutions of 10 mM Al₂(SO₄)₃, 100 mM Fe₂(SO₄)₃, and 100 mM Na₂SO₄.
• Combine the above stock solutions with 944.5 nM porphine made on 2012/10/17.
• Conduct UV-vis spectroscopy on the porphine-salt solutions.

UV-Vis Spectroscopy on 944.5 nM Porphine and Salt Solutions

• For all solutions, 1 mL of salt, 1 mL of 944.5 nM porphine, and 8 mL H₂O were combined.
