SOLUTION STOICHIOMETRY AND NEUTRALIZATION REACTIONS
EXAMPLE 1: Calculate the mass of solid NaCl that must be added to 1.50 L of a 0.100 M AgNO3 solution to
precipitate all of the Ag+ ions in the form of AgCl. Calculate the mass of AgCl formed.
EXAMPLE 2: Calculate the mass of solid sodium sulfate that must be added to 250.0 mL of a 0.200 M solution
of barium nitrate to precipitate all of the barium ions in the form of barium sulfate. Also calculate the mass of
barium sulfate formed.
EXAMPLE 3: Calculate the mass of NaI that must be added to 425.0 mL of a 0.100 M Pb(NO3)2 solution to
precipitate all of the Pb2+ ions as PbI2. Also calculate the mass of PbI2 formed.

Document Summary
Example 1: calculate the mass of solid nacl that must be added to 1. 50 l of a 0. 100 m agno 3 solution to precipitate all of the ag+ ions in the form of agcl. Example 2: calculate the mass of solid sodium sulfate that must be added to 250. 0 ml of a 0. 200 m solution of barium nitrate to precipitate all of the barium ions in the form of barium sulfate. Also calculate the mass of barium sulfate formed. Example 3: calculate the mass of nai that must be added to 425. 0 ml of a 0. 100 m pb(no 3)2 solution to precipitate all of the pb2+ ions as pbi2. Example 4: when ba(no3)2 and k2cro4 react in aqueous solution, the yellow solid bacro4 is formed. Calculate the mass of bacro4 that forms when 0. 00350 moles of solid ba(no3) 2 is dissolved in 265 ml of 0. 0100 m k2cro4 solution.
