27PRACTICE PROBLEM
A solution of Pb2+ is produced from dissolving 0.617 g of impure lead sample in strong acid. This solution needed 0.0263 L of 0.0568 M solution of NO3- to reach the equivalence point where NO3- is reduced to NO gas. What is the mass percent of lead in the sample if there is no other reducing agent?
