A standard addition method for the voltammetric determination of Pb2+ involved addition of 5.00 mL of 0.800 x 10-3 M Pb2+ to one of two 25.00 mL aliquots of the sample. Supporting electrolyte and water were then added to each aliquot to give a final volume of 50.00 mL. Calculate the molar concentration of Pb2+ based on the following data Diffusion current of sample only = 78.3 uA A Diffusion current of sample with standard addition = 88.7 uA

Question

A standard addition method for the voltammetric determination of Pb2+ involved addition of 5.00 mL of 0.800 x 10-3 M Pb2+ to one of two 25.00 mL aliquots of the sample. Supporting electrolyte and water were then added to each aliquot to give a final volume of 50.00 mL. Calculate the molar concentration of Pb2+ based on the following data

Diffusion current of sample only = 78.3 uA

A Diffusion current of sample with standard addition = 88.7 uA
