SOLVED:The concentration of lead ions (Pb^2 ) in a sample of polluted water that also contains nitrate ions (NO3^-) is determined by adding solid sodium sulfate (Na2 SO4) to exactly 500  mL of the water. (a) Write the molecular and net ionic equations for the reaction. (b) Calculate the molar concentration of Pb^2 if 0.00450  g of Na2 SO4. was needed for the complete precipitation of Pb^2 ions as PbSO4.
