4. The tetraethyl lead [Pb(C2H5)4] in a 25.00-ml sample of aviation gasoline was shaken with 15.00mL of 0.02095 M 12 . The reaction is: Pb(C;Hs), + ½ → Pb(C,H;)gl + CzH,l After the reaction was complete, the unused 12 was titrated with 6.09mL of 0.03465 M Na2S203. Calculate the weight (in milligrams) of Pb(C2H5)4 (MM 323.4) in each liter of the gasoline. 25,0,2 + l2 → 21 + S,O,² Answer: 2.70 x 10° mg/L gasoline
