The Concentration of lead ions(Pb)2+ in a sample of polluted water is determined by adding solid sodium sulfate (Na2SO4 to the sample. The net ionic equation of the reaction is: [ (Pb)2+ (aq) + SO4(2-) (aq) -------> PbSO4 (s)
How many moles of (Pb)2+ did the sample contain if .00505g of Na2SO4 was needed for the complete precipitation of lead ions as PbSO4?
