OBJECTIVESPorphyrin Salt Selection and Preparations 2SO42- salts used:Fe2(SO4)3, Al3(SO4)3, FeSO4, & Na2SO4 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 Fe2(SO4)3: 278.91 g/mol 10mM Fe2(SO4)3 × (100mL H2O / 1000mL H2O) × (278.91g Fe2(SO4)3 / 1 mol Fe2(SO4)3) = 0.2789g Fe2(SO4)3
MW Al3(SO4)3: 356.37 g/mol 10mM Al3(SO4)3 × (100mL H2O / 1000mL H2O) × (656.37g Al3(SO4)3 / 1 mol Al3(SO4)3) = 0.6564g Al3(SO4)3
MW FeSO4: 278.01 g/mol 10mM FeSO4 × (50mL H2O / 1000mL H2O) × (278.01g FeSO4 / 1 mol FeSO4) = 0.1390g FeSO4
MW Na2SO4: 142.04 g/mol 10mM Na2SO4 × (100mL H2O/1000mL H2O) × (142.04g Na2SO4/1 mol Na2SO4) = 0.1420g Na2SO4
