A water supply was known to contain lead (II) ions. A 100.0 mL
aliquot of the solution was pipetted, and its mass determined to be
100.53 g. The 100.0 mL aliquot was acidified, and 21.25 mL of a
0.01235 M potassium dichromate solution were required to oxidize
all of the lead (II) ions. Calculate (1) the molarity of the lead
(II) ions in the solution, and (2) the mass percent of the lead
(II) ions in the solution.
