OBJECTIVES
Porphyrin Salt Selection and PreparationsSO_{4}^{2} salts used:Fe_{2}(SO_{4})_{3}, Al_{3}(SO_{4})_{3}, FeSO_{4},& Na_{2}SO_{4} Preparing 100mM Stock Solutions For Each Salt :
(Ensure that the volumetric calibration line is not surpassed or solution must be remade.) 100mM Salt Solution Calculations
MW Fe_{2}(SO_{4})_{3}: 278.91 g/mol 100mM Fe_{2}(SO_{4})_{3} × (100mL H_{2}O / 1000mL H_{2}O) × (278.91g Fe_{2}(SO_{4})_{3} / 1 mol Fe_{2}(SO_{4})_{3}) = 2.8791g Fe_{2}(SO_{4})_{3}
MW Al_{3}(SO_{4})_{3}: 356.37 g/mol 100mM Al_{3}(SO_{4})_{3} × (100mL H_{2}O / 1000mL H_{2}O) × (656.37g Al_{3}(SO_{4})_{3} / 1 mol Al_{3}(SO_{4})_{3}) = 6.5637g Al_{3}(SO_{4})_{3}
MW FeSO_{4}: 278.01 g/mol 100mM FeSO_{4} × (50mL H_{2}O / 1000mL H_{2}O) × (278.01g FeSO_{4} / 1 mol FeSO_{4}) = 1.3901g FeSO_{4}
MW Na_{2}SO_{4}: 142.04 g/mol 100mM Na_{2}SO_{4} × (100mL H_{2}O / 1000mL H_{2}O) × (142.04g Na_{2}SO_{4} / 1 mol Na_{2}SO_{4}Na2SO4) = 1.4204g Na_{2}SO_{4}
UVVis Spectrum of Porphyrin with SaltsA specific porphyrin solution (944.5nM) was selected for exemplary UV  Vis analysis pertaining to each salt. Furthermore, 0.1mL each salt was combined with this particular porphyrin solution. Notes
