OBJECTIVES
Porphyrin Salt Selection and Preparations 2SO_{4}^{2} salts used:Fe_{2}(SO_{4})_{3}, Al_{3}(SO_{4})_{3}, FeSO_{4}, & Na_{2}SO_{4} Preparing 10mM Stock Solutions For Each Salt :
(Ensure that the volumetric calibration line is not surpassed or solution must be remade.) 10mM Salt Solution Calculations
MW Fe_{2}(SO_{4})_{3}: 278.91 g/mol 10mM 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}) = 0.2789g Fe_{2}(SO_{4})_{3}
MW Al_{3}(SO_{4})_{3}: 356.37 g/mol 10mM 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}) = 0.6564g Al_{3}(SO_{4})_{3}
MW FeSO_{4}: 278.01 g/mol 10mM FeSO_{4} × (50mL H_{2}O / 1000mL H_{2}O) × (278.01g FeSO_{4} / 1 mol FeSO_{4}) = 0.1390g FeSO_{4}
MW Na_{2}SO_{4}: 142.04 g/mol 10mM Na_{2}SO_{4} × (100mL H_{2}O / 1000mL H_{2}O) × (142.04g Na_{2}SO_{4} / 1 mol Na_{2}SO_{4}) = 0.1420g Na_{2}SO_{4}
